Ever since this morning's update I'm having to re-enter my pin any time I hop worlds. I have the setting to not need to do that on, and this is happening for several people I know.
"Players report having to re-enter their Bank PIN after every world hop. The team are investigating and have a fix prepared, but the solution needs to be deployed via coldfix. We expect to launch this fix alongside next week's Game Update, on Wednesday, July 26th."
