Chat stops auto scrolling when you scroll up and clear chat.
Reproduce: Have a chat channel with enough chat in it to show the scroll bar and then scroll. Now clear all chat and wait until chat fills up enough to show the scroll bar again and it will not auto scroll. This is especially bad for intel channels. I often don’t even notice it until later on which obviously is not good. lol
NOTES: You can even scroll back down before you clear it and it will still do this. There is also no way to fix it unless you either relog or reopen the channel. Only solution is to just not clear chat. (Sorry OCD peeps)
