I get this error when i'm doing a best in bag:Index was out of range. Must be non-negative and less than the size of the collection. Parameter name: index
What could it be?
We're doing an update shortly with some more 7.2 stuff and a few bug fixes, this error should be fixed with that.
EU player here with the same problem.
My guess is, AMR is already "patched" to 7.2 while the EU live server are still on 7.1.5.
edit: i read yellowfives comment after my post. so ignore mine
