I am working on a small game for a uni course and we are required to use blueprints. But unreal has started crashing when I edit them. Any solutions or ideas would be greatly appreciated. I will provide any info that might help. Thanks.

I tried to edit a blueprint. And I was expecting to not crash consistently.

Answer 1

I figured it out. I was editing child actor templates. Which you are not allowed to do even though it lets you. I started creating child blueprints instead and that solved my problem.
