When moving through a level I tried to hit a spell key but accidentally opened my Skill page and panicked. Upon closing it I could no longer move my character unless I was clicking on an item or gold. Rebinding ‘move’ didn’t help.
I managed to figure out what I did, fix, and replicate the issue.
If you open the ‘Skills & Specializations’ page, and click and drag a skill, then close the page with Esc while still holding the mouse button down, when the page closes you can no longer click the ground to move.
To fix you need to go back into the Skill page and drop a skill onto the skill bar (can replace a skill with the same one)
