Celtic Heroes

Hello, few hours ago, a girl couldn't be attacked, i tried to, everyone tried i guess since they were jumping each other. But she couldn't be touched. I asked her and she said that she didn't know how, she just logged into the game and then it happened. So it was a glitch or bugg. Later on, none could move inside the arena and a few others also couldn't be attacked. Fix this pls. But it was funny.

Pretty sure it has to do with lowering graphics which results in a re log. Arena is
just glitchy n buggy AF anyways. I can remove a players stun skill by just simply swapping a different item on lol. Fix this bug too.
