NPCs able to be stuck as busy until server restart
Neq Today at 1:47 PM:
Problem: NPCs can be made stuck in the "<NPC_name> is busy at the moment" state permanently, until the server is rebooted.
Replication steps: Click an NPC to talk to them. Immediately, before the dialog begins, open the settings menu. After your character starts talking to the NPC and it comes time for you to choose a dialog option, then click the "Click here to logout" option. You'll be logged out. After you log in again, you won't be able to talk to the NPC because they'll be stuck in the "<NPC_name> is busy at the moment" state. Only a server reboot fixes it and lets you talk to them. I'm on Android 4.2.0 RSCCabbage.
I've currently frozen all the NPCs in Catherby bank while testing replication of the bug.
