So I made a charcter for my brother in Tennessee yesterday before he went home. Someone is dropping single gold coins in the new player bins to prevent us from putting in equipment. I have put in a help request but maybe this will get +C's attention
This. ^ Once you're past the new player status, you can't open those chests at all - just drop stuff inside. Unless there's a way to do it with a macro, the gold would auto-stack.
