Since the update, I cannot type in chat, trade windows, or the AH at all. I also cannot enter a password to login on my alt (fortunately my main is on Steam). I can play normally, and all my other keybinds work fine. I can also copy and paste into chat and send messages that way. I am on Linux Mint, which is likely the reason it isn't working. I would have reported this in game but I could not type in the F2 menu either.
Also, the game audio sounds muffled/weird. I've heard the same from multiple people so I know that's not unique to me.
Since you cannot file a bug, can you please send over your projectx.log so we can take a look? You can either paste it here or email it to support@spiralknights.com
