[Main Thread] Chat windows resetting

Chat windows are all messed up!

There appear to be a few UI issues that are being looked into, so if it is happening with the default UI, it is likely among them and likely being looked into. I would still recommend posting in the Bug Report forum and maybe adding to any existing threads with details on what you are experiencing.
