Raid problem, dissapearance and bug?

Well hello, i wanted to report, since the update i haven't tried the raid system and how did it work until trying normal combat and PvP which were pretty fine by the way.

But when i tried the raids (i joined 2) the first one started, i contributed and all that, and when was time to finish, the raid, never finished, but also never appeared in the upcoming events or finished raids tab, the second one started (both of the raids had an error with my timezone too, but i saw some reports about it so that's not my point), i also contributed in the second one, the raid finished and it said that neither one of the people in the raid or me contributed, when, both of us, in fact, tweeted a lot.

I'm sorry if somehow my english looks broken, not a english speaker, thank you very much for reading this!
