My char was banned for invisible bug?? oO

Why was I banned? I went into shadow walk and not skirt ... I thought it was some server upgrade. Not too soon because I work all day, my son also plays on my acc, but did not see anywhere that it was bug in the game ... After all, it is not easy you mend this kind of thing than to be banning players so abruptly??

I also saw some posts here that other players also took ban for "using" this bug ... but a ban for 3 days. How will the situation get out of my account??

Thanks ...

 

Invis bug is only a 1 day temp ban.
