[CLIENT] Error message after receiving many invitations

Hello guys

It's bonus IP week you know, and many people join chatrooms where they seek for 5 men premade. The problem is, that after receiving too many invitations ( something between 20 and 30 ) the client starts reporting error after every new invitation. This can be really annoying, because you have to click OK manually on every error or restart the client - which means you got disconnected from chatrooms and they may be full when you want to rejoin again. So clicking OK is the only option. This can be really tiring when you have to click on it like 50 times and new and new invitations are still incoming. ( See the screenshot for error example )

Thanks for reading ( rito fix plz )
