While setting up a server I had my addons enabled, and when I went to type the title I hit backspace to erase the previous title just to find out the only buttons working was the backspace, enter, escape, and ~. I shrugged it off and started the server and upon spawning I tried typing in a command, but it just came up with a gui that's bound to my / key when not typing.
This just happened today and restarting blockland doesn't help.
