Yes, looks similar but I can successfully package the game. Crash occurs at runtime both in 4.12.5 and 4.13.1. UE-35734 is opened for version 4.13 too but it says that it doesn’t build at all.
As you see at my functions graph, it doesn’t include an open input. Or are these considered as open too, since it defines it’s variable by itself? But it is still not failing the packaging process.
