And I got asset wrong. it was BP_CapacitorBank02. Moving it back to original location still results in a crash. log says “invalid generated class for ScructureFunctionLib”. I remember I did do something to a funcion in that library - I made it a pure function, as I thought that was what was messing it up before.
I think root cause of problem was that I copy-pasted some nodes from one blueprint to another, and everything after that was in effort to fix it.
Sorry for confusion
