We've worked out H Vizier for two nights now, and both nights we had to stop working on him early because he evade bugs and refuses to despawn. It's not consistent either.
The first time it happened, our Hunter tried to despawn him after a wipe by Feigning. He didn't despawn and just stood there doing nothing. The Hunter tried getting back up, and nothing happened. He was evade bugged. Hunter went into the gas and died, and still nothing. We tried disbanding, resetting, reforming, and going back in, and we couldn't set it to heroic because everyone had their own heroic raid lockout allofasudden.
The second night, we had a wipe and someone still up with MC. The same thing happened with the boss going inactive, but not despawning. The MC'd person had to alt+f4 out of the game to come back in, and again, same shit, different day.
We've had a grand total of about an hour and a half to work on this guy over two nights because of this bullshit. Tickets put in just said they'd forward our tickets to QA and that they can't reset raid lockouts. A google search found blue posts saying the only workaround is to wait a half hour to reset the raid instance.
Has this happened to you? Is this common on this guy?
