i upgraded a templar to 5 stars so i can use it for upgrade an aothar to 6 stars. I unlocked the templar and selected "sacrifice" after the windows popped up. Despite i selected "sacrifice" nothing happens. The templar seems stucked and unusable. It happens only with this hero, the others works normally. I tried restarting the game and start it on various devices but the bug still remains.
