Editor crashes on map save [4.6.1]

Hey everyone! I’ve got a project I’ve been working on for a few days now, trouble is whenever I attempt to save my map the editor crashes on me. After this happened I decided to cut my losses and figured the file must have been corrupted or something so I copied the BSP from the old map and rebuilt everything else (there wasn’t a whole lot, just slap a couple of blueprint objects in and link them up in the level blueprint). Now the new map file is crashing on save as well and I have no clue why. I’ve attached the log and if anyone has any idea what is wrong please let me know, this issue is turning what was supposed to be a quick fun game-jam into a nightmare.

EDIT: Aparently the Log is an “unsupported format” so I’ve put it here. Sorry for the massive length!

Hey Kibitz,

This is a known issue and we’re investigating it now. Just out of curiosity, are you using Event Dispatchers at all in your blueprints?

Yes I am, I have a class blueprint that takes an on clicked event which calls an event dispatcher used in my level blueprint to call an event in a separate class blueprint. I just switched to that system, before I was simple calling the on clicked event straight from my level blueprint.

If you remove the Event Dispatcher, that should eliminate your crash. We’re working on a fix for this bug, but that should allow you to work around it.

Thanks! That worked! Good luck on the fix Dispatchers seem like something that could be a lot of fun to mess around with in the future!

Glad to help. We’ll deploy a fix as soon as one is ready.
