Was playing in apartments when suddenly I got the bug where cursor suddenly pops out midgame and you have to press esc or w/e to be able to move your screen again with a mouse. Then I noticed after dying next time that my class was taken and I had to pick a new one. I wonder if the cursor bug could've been caused by someone picking my class while I was playing? If so, could this be a clue as to what causes the cursor bug?
