Tried many permutations of linked image- initially I was inheriting Perception from a Parent Class GameAI to a ChildClass AICharacter. Everything worked fine. At one stage I put AIPerception on the child as well as parent (not intentionally, just happened, I understand why I wouldn’t do this).
One day things stopped working, and now no longer work in their most basic form in this blueprint. When I plug this OnTargetPerceptionUpdated (AIPerception) in, I can play in the level fine. Perception works! It works 100% of the time and never just crashes straight away.
When I quit unreal engine however, it crashes (if I push to source control, other computers also crash until I rollback the said AICharacter file. I think when I reload Unreal Engine the crashes fluctuate between on boot, and on loading a level.
I have tried with AIPerception on only the parent, only the child, w/ different configurations on detection by affiliation, and with and without an ai stimulus source on fpscharacter (my debug character). All crash, with the exact same pattern.
