Strange but funny Glitch

This happens a lot on private servers haha, I've played them for a long time and experience this on every server. You can actually still type in your password and get into the game, once you're at the character selection screen or in game the message will go away ^^. Or you can restart your client but that isn't necessary unless you really messed up typing your password or accidentally clicked where you username goes haha.

 

Happens when you start a chat with another NPC while current one still hasn't fully ended (for some NPCs, there's a short intermediate period where the current NPC chat disappears then loads the next set of chat).
