We are getting the same problem.
We’ve implement our own node for animation blueprint purposes. Everything works fine, If the game is running with cook mode, but when we run the game with uncooked (i.e., running the editor with -game parameter), it crash in:
“PruneIsolatedAnimationNodes” method. AnimBlueprintCompiler.cpp in the next line:
UEdGraphNode* OtherNode = OtherPin->GetOwningNode()
Anybody knows how to solve this problem??
I will post any clue.
Thanks in advance,
