Hey Guys,
I just had a crash while editing one of my Blueprints. It was a Blueprint that had a bunch of TextRenderComponents and when I deleted a given one, replace it with a ChildActorComponent, and gave the ChildActorComponent the same name as the original TextRenderComponent, it crashed and gave me the following log… hope this helps
Note: If you see this TJ, after looking at the log, it seems to be related to Slate just like the previous bug. Different but maybe related to the fix that was taken care of in my previous post. If another team member sees this first, here is a the previous post I mentioned. Found another bug in 4.4.0, this one is odd, guessing its a Slate bug - UI - Unreal Engine Forums
Crash Log Below:
Fatal error!
UMaterialInstanceDynamic::`vftable’() Address = 0x40903180 (filename not found) [in E:\Source\UnrealEngine-4.4.0-release\Engine\Binaries\Win64\UE4Editor-Engine.dll]
Looks like it is happening again with the same series of events and I left two other steps from the previous comment. I also set the Location, Z: 100 for my item and clicked the Visible Checkbox. I’ll try it again and see which one it definitively crashes on.
I was in the process of trying to replicate this and missed a step so I tried to close UE4 and got the following crash…
Fatal error!
Address = 0xc3e03a00 (filename not found)
I am going around this for the time being and doing a different set of steps with a lot of re-saving and I can get around it for now. I did get some more unrelated crashing so I think I am going to upgrade everything to 4.4.1 this weekend to see if some improvements happen to fix some of these issues. Thanks again guys.

Hey MC Stryker,
Thanks for the feedback. I’ll look into this and see what I can find out.
Sounds great TJ, good luck looking into it and if you want me to try and replicate it and maybe get it on video again, let me know. This weekend is going to be pretty busy but if you need it and I can hopefully get it to happen again, I’ll get a video posted for when you get back to the office on Monday. Take it easy TJ

Sounds good. Monday is a holiday for us, so I’ll be back on Tuesday. Have a good weekend!
Oh that’s right, haha. Forgot about that. Cool, well I’ll try my best to document some stuff and hopefully I can come up with a pattern to replicate the steps. Take it easy and enjoy your weekend/holiday TJ, we’ll catch up next week.

Hey TJ, just wanted to let you know I haven’t forgotten to attempt to replicate it again but I’ve been very busy and may be booked through the week. I’ll try to do this asap so I can hopefully provide you and the team with more info. Hope you enjoyed your holiday and take care.

I haven’t been able to get a repro yet, so any additional info will help. But whenever you get time is fine. If it’s not a showstopper for you then we can come back to it later.
I had a great holiday, thanks for asking. Take it easy.

No worries buddy and glad to hear you had a good holiday. Between a call I have with Microsoft on Friday and building a new workstation, it’s been crazy to say the least but things should free up by this weekend or Monday at the latest. I’m in the process of trying to pitch Microsoft my game for a publishing contract and my friend who runs Global Community Management at EA on the Battlefield series is trying to get me in EA and Sony as well. It’s been a long time dream to start my own video game company and I’m getting down to the wire to hopefully raise the funding.
Actually, when I left my job, the Friday before is when UE4 dropped and I’m not kidding that literally the night before, I was sitting there going over press info and videos on Inside Unreal wishing that it would come out and it did the next day. Since then I’ve been working from early till roughly 5am every night trying to get the content, functionality and idea of the prototype while also trying to learn as much about business and fund raising but it’s starting to come together. I’ve been chatting with Microsoft for a while through email and have been a member of the ID@Xbox program since last year but Friday is literally the first real opportunity to pitch them that’s not email so I just personally need a little bit of time to give it my best shot.
But thank you for the patience and I will definitely get to it by Monday one way or another TJ. Even though I found a way around it, I still have to convert a couple more of those TextRenderComponents to that new ChildActor I created so hopefully I can get it to happen. I’ll keep you posted and looking forward to the stream tomorrow. Take care TJ.

Okay TJ, sorry about the delay. I was able to make it happen once but I wasn’t recording yet. Every other time it actually threw an error in the compiler results. I am having a problem getting my video off my phone that shows me attempting to do that and for some reason, Windows isn’t seeing it. But basically what I did what have a TextRenderComponent with a name like ‘Options’ for example. In my case, it was attached to a SceneComponent. Compile it and once everything is good to go, try closing the editor, going back in, deleting ‘Options’, then adding a ChildActorComponent to that same root. Rename that as ‘Options’, then hit Compile and see if it crashes. It seems like maybe after it crashes, it then throws an error that TextRenderComponent ‘Options’ does not exist in the Compiler Results. Anyways, hope that helps and I’ll let you know if I see it again. Take care

I just attempted to reproduce this in 4.4.0 from Github, 4.4.1, and on another PC and I still can’t get your results. Perhaps recompiling the editor could fix it?

It’s possible. It did happen though in my 4.4.0 source before I upgraded it but it only seemed to crash once. I upgraded to 4.4.1 but you never know. It’s possible and what I’ll do is after the busy part of the day, I’ll go try this again and see if I can get it to happen. The only thing in my case that was different that I could remember is that it successfully was compiled already before doing those steps. I’ll try again today and see if I can find it. What I’ll also do is run the editor in the Debug Editor configuration and see if I can catch the line in the code that is throwing the exception and see what is conflicting. I had a serious face palm moment when I tried it and got the crash but wasn’t recording the video so I’ll see if I can catch it. I always hate elusive bugs like this because for as little as it’s crashing now, just trying to find the prerequisites can be a pain. But I’ll try to update you later today TJ and see if I can get it to happen.

Hey TJ, really apologize about the delay. I am gearing up to work on the Main Menu right now so I’ll try and replicate it and catch this on video so we can close out this ticket for you. I’ll probably have some sort of response shortly as it will be the first thing I’ll be addressing here. I’ll keep you posted…

We Got One!!!
Alright, I got it on video and will be posting this shortly. I am also going to try and take a video of what happens when you go back into the engine as it may give you and the team more insight on the issue.
For the meantime, here is the crash log that just happened…
Fatal error!
Address = 0x839d2c00 (filename not found)

Here is the video link TJ… Microsoft OneDrive - Access files anywhere. Create docs with free Office Online.
I mentioned a second video in this one but it wasn’t needed. What I thought was an additional symptom was unrelated.

Awesome, thanks for the video! I’ll see what we can figure out and post back here to let you know.
I saw your other post as well, I’m glad your back in the project. I have asked one of our devs to look into that one too.

I don’t remember if you are using Source or not, but I just found out that one of our devs put up a fix for this on GitHub. If you merge this file into your version of the editor it should correct the issue.

Thanks for the link. Actually I am using the editor from source so that will help! But glad it was able to be repro’d. Thanks again TJ!
