Raid lock

Hello,

I could not find any new threads about "fixed" extended raid lock, so there I go.
Everything happened on Lordaeron.

Two weeks ago we did ICC10 11/12 with LK alive, had an idea to use raid lock to extend the raid to the next week. Comes the next raid day and we try to kill LK with raid lock option. At the beginning it looked like the raid lock worked fine. 11/12 dead, LK alive and we could start the fight by talking to Tirion. However after the roleplay event, as the combat should start the whole raid was teleported to the entrance of ICC, it happened every time we tried it.
Then we decided to see if any other bosses are alive and we found Valithria to be there. So we started her fight and noticed that the encounter was bugged, vali was attacking every enemy that spawned and moved around the room. We healed her fully and loot chest appeared with some items.
However, the fight did not end, mobs spawned endlessly, we wiped and the encounter did not end, more mobs kept spawning and event after everyone left the instance, encounter did not end and no amount of reset was helpful.

Have no photos or anything like it to prove that anything above happened.

tl' dr: extended raid lock bugged the next weeks encounter.

The function to extend raid lock is still bugged and should be looked into.
If anyone has something to add, please do.

Regards,
Andrius
