I’m trying to move my project from 5.5 to 5.6.1 but all the maps we made crash the engine if we touch anything! Just moving some objects crashes the whole engine as soon as we click PIE.
I have no idea how to reproduce this I’ve tried isolating an object but when I start deleting everything the crashes go away but I cant delete my whole game and start from scratch what the hell!
Every single time the crash message is exactly the same:
Caught signal 11 Segmentation fault

What can I do to figure out what’s causing this?
