We disbanded the raid completely and only half of our raid is able to zone into the reset version of Heart of Fear. The other half of the raid appears to be locked to the version with bugged Vizier for some reason.
We've tried making one of the non-bugged raid members the raid leader and having them zone in first. That didn't work. We tried having everyone log out and in. That didn't work. We tried having the bugged people use the Reset Instance feature. That didn't work.
We request that something be done to reset all of our Heart of Fear lockouts completely so that we can continue to raid tonight. Please and thank you. If you need further information, let me know here, or whisper me or our raid leader/GM "Romoredux" in-game.
Edit: We are going to attempt to hard reset the raid by not zoning into Heart of Fear for 30 minutes. We'll let you know if this does not work.
