Using the window interface B or C for a 2000 battle can cause softlocks when displaying some messages

[Mimigris]

Was testing this with the command Set Interpreter Flag on a 2003 game, and encountered this issue.

For instance, here in this test, if you try to run away and fail, after the message "Couldn't escape!" is displayed, nothing will happen and the battle will be stuck.
