FT Account name: Fader
Time of bug: 9:55pm on Sunday June 11th at my place
Where: Ascanius library
What: An outlaw player level 77 come attack me
I stun him and about to attack. But when I hit the attack button I don't attack him, then I die fast and lost my amulet level 100 to him
Why: the attack button does not work!!
Other comments: I want to take my AMULET back(I farm a lot to get it and can't lose it because of this:v) second I want this won't happen to anyone else because I feel very bad after that
