Wont happen …
Something is wrong in the crate drops. I have seen this before in these forums. The other person didnt even touch the supply drops, yet, he was getting the exact error.
I dont know the resolution, because, he never came back to say “this was the error, this was the fix”
“SupplyCrateSpawningVolume” on several different cpp lines (cpp=c++ for those that dont know)
I would even venture to open the build of it and see whats happening. I forgot if yall have that ability tho. I think they removed the source line from Ark. Hmmmm … either way, something in your BP’s maybe wrong. Since thats what the cpp would correlate to. Maybe you made a change to something that effected another child some place. I dont know if all “supplycrates” are connected, or, whats a parent/child of them. Without knowing what you were modding, i dont even know where to start.
