Teamlers aka GO SGO GA dont have any connection with events etc. That is all "production" team. Learn the difference, and for the matter of this situation I belive all players are really pissed.
Gameforge should better fix this with something that can compensate all buffs or some stuff like that.
I think people wasted so much money and time in this game and they get stuff like this. Shame, that's not how you show love to community that gives you paycheck or at least "bread" on table in any other way.
