Crash From Linked BPs

MC_Stryker · September 25, 2014, 7:52pm

Hey Guys,

So I received this crash in the past and it’s definitely gotten better in subsequent builds of the engine however it still persists but now I’m starting to notice a similarity with the issue. I was working with TJ Ballard on an issue having to do with my MainMenu Blueprint where I now have a MainMenu BP, that has ChildActorComponents that reference my MainMenuItem BP for each item in the menu.

I am going to switch these over to just using interfaces and have no reference to either BP to hopefully fix this, but what I’ve noticed is if I have my MainMenuItem BP open and the MainMenu BP open at the same time, I get the crash from below. If I have just my MainMenuItem BP open and compile it, it’s fine. Then I can move onto re-compiling/saving the MainMenu BP from there. So it is appearing to be and I’m not 100% sure but I think it’s only conflicting when the BPs with dependencies are open at the same time.

EDIT: Okay, doesn’t seem to be affected by the top-most BP, but the base class MainMenuItem if compiled with others opened did crash it. I also noticed this with other BPs in the past that the crashing is more affected by attempting to compile the base BP’s than the ones that rely or use them. I also have CastTo as well as have components that represent those MainMenuItems so I’m going to eliminate any dependencies and if I have variables that store those types, I’ll store a more generic native type such as Actor and use an interface to get access to it. I should be able to do that without them losing any features. I’ll let you know how that goes but try out what I mentioned above and if that doesn’t work, I’ll give you access to my BPs that are failing on a pm on the forums. Thanks again!

Hope this helps!

Hi MC Stryker,

Could you also post your LOG and DMP files?

MC_Stryker · September 26, 2014, 8:56pm

Sure TJ! What folder are they stored in?

TJ_V · September 29, 2014, 1:34pm

.LOG and .DMP files are in: [project]\Saved\Logs folder

MC_Stryker · September 29, 2014, 7:42pm

Hi TJ! Hope you had a good weekend. So here is the link to the logs…

I’ve had a ton of random crashes since then so I matched up the timestamp of my post to the closest dmp and log files. I think the dmp included was at a later time but was the next one to follow so I threw it in. If you want me to get the dmp from the time before that one, let me know but the log is marked 7:45pm on the 25th so that should be the one from that time.

Thanks TJ!

Hi Andrew. I can see you posted an answer to this question but it is not showing in my internet browser. I can read the answer from my email and you are saying that there have been subsequent version updates since. I’m not sure if I received an answer you posted to another question but for this one, I am using version 4.4.3 which is the most recent version number so I am guessing there is a bug with answer hub and I am receiving your answer from another post.

Hi MC Stryker,

Sorry about that. Just ignore that comment, I deleted it. Some of our team was going through backlogged issues and somehow yours got hit.

MC_Stryker · October 15, 2014, 9:24pm

Thanks TJ! Sorry about the delayed response. For the time being, let’s call this resolved for your tracking purposes since I’ve upgraded to 4.5 and if I see it again, we can simply re-open the thread. Hope all is well buddy.
