Fatal errors logs while loading and random crashes

Development Programming & Scripting

My project was working fine until now I just open it to start working and show this fatal errors in the log after loading then it craches randomly later after ending the play in editor. The game works as expected without problems.

I removed the nodes that seems to be conflicting then recreated and saved, anyway the errors apears again when I load the projects and the annoying random crash after playing in the editor.

Something superstitious: I save the level, then run the game and when exited the level appears as modified and need re-save. While I have not modified anything just click Play and nothing else.

Level blueprint is always dirty after playing game, it says need to be recompiled… :frowning:

Hey piXelicidio,

Are you using 4.6? Crashing when ending Play In Editor is a known bug in 4.6. It’s fixed in 4.7.

Are you seeing any other issues related to the error messages?

Regards,

Jonathan

Hi Jonathan, I’m using 4.6, I will try 4.7.
But the crashes actually occurs randomly when I open another level after some time working with my blueprints.
Please check this other question I posted with log files and screenshots: Crash: Loading a new level from the editor "(level) still around trying to load" - Community & Industry Discussion - Unreal Engine Forums
Happy new year.

Hey piXelicidio,

Could you try removing the Event Dispatcher from your blueprint to see if that fixes it? We’ve got a known issue where Event Dispatchers are causing crashes, and this may be related.
