Have all of the crashes you experienced happened in a new function? Additionally, what variables did you change from/to?

Hi Furroy,

Are you using any event dispatchers in your project by chance?

I didn’t even know what those were until I just googled it now.

Thank you for the update. Do you have a project that these crashes are occurring consistently in? I’d be more than happy to take a look at it.

I guess so, is there a private place I can upload a zip to? Also, it may not be true but I get the feeling that the crashes happen more frequently if I have more editors opened and more function tabs open on each one.

Hi Furroy,

You can message me a link to the download on the forums so that no one else can see the project. I’d be more than happy to take a look and have already cleared out my inbox to make sure I don’t miss it. How many editors/function tabs do you typically have open at one time?

Link sent on the forums. Hopefully I set up the file sharing rights on Google Drive properly, if not, let me know!

Hi Furroy,

I got the project and have been unable to reproduce this on my end. I have attempted opening every blueprint you have in the project and adjusting variables in all of the functions that I saw but adding/altering inputs and compiling. Other than a single copy of the editor, do you have any other programs running at the same time?

Firefox, Photoshop, and Blender. My laptop has 16G of RAM.

Try closing those programs in the back and see if it works. If it still crashes try turning down the scalability settings.

Hi Furroy,

I am going to mark this as answered for tracking purposes. I have entered a bug report for your crashes, as reported here:

I believe that your specific crashes are all being pulled from the same general error, which appears consistently throughout your crash logs. If you run into any more crashes please don’t hesitate to upload them so we can try to get to the root of what is occurring. Thank you!
