it is not because of my teleporter i know that now after deleting an entire map, content by content, untill there was literary nothing left. but just for the sake of it heres the picture:
I think there are some settings concerning the packaging process. I am not familiar what the standalone does concerning packaging, but there is something in the project settings that handles the packaging of all the levels. I stumbled accross that one time, but I don’t know where exactly it was and if this could help you.
Maybe you checkout the packaging stuff in the project settings.
