For some reason just out of nowhere, woke up this morning, joined a bg, one of my binds stopped working. Tried to rebind it. Realised the game won't let me bind alt 1 or 2 etc any more. No idea why. Disabled bartender. Deleted bartender. Installed Dominos. None of them let me bind to alt + any number any more. I don't get it. Something to do with a modifier apparently which I disabled.
