There is a bug in Human: there is some chance that a hero after being saved by Staff of Sanctuary cannot move, even after his HP is full.
(I just met this bug after sending my Pala back, but it cannot move, even after I used the staffs by AM and MK to move him twice. It was against UD, and the T3 town hall was damaged to about a quarter HP, and repaired to full HP. If it helps me debug.)
I think there is some match replays on Youtube of some Pro Human players. Could you please help check and fix this bug?
