Issues after getting Dc hacked

So, yesterday I was dc hacked by a random guy on FM, he locked me or something, I was still in game but I couldn't enter any permit in there, he talked to me and said " sorry but you'll be dc in 20 seconds" after that I can't enter class warfare and don't even get the mystic boss notices. Anybody knows about this?

Mystic gates are broken and no one can get into the class warfare rooms. It has nothing to do with you being DC hacked.

Thanks for your reply, I didn't know about those issues.
