Here's the current issues with Ulduar we're currently investigating or are known and have no current fix.
Siege Engines that use Steam Rush while on a ramp sometimes fall through the world.
We currently have no fix for this, the workaround is simply to not cast Steam Rush on the ramps. The ability works fine in the Flame Leviathan fight and other flat ground.
Ignis sometimes will slag pot the offtank dealing with constructs.
The protections in place work most of the time, but we're still investigating reports on this. Note that the protection is only granted if the tank is actively being melee'd by the construct. If players immobilize the construct and the tank backs away, the tank will not have the slag pot protection.
Kologarn can Stone Grip someone at the exact same time his right arm dies, leaving the player gripped for an extended time.
This is really rare, we located the issue, but a fix will have to wait for a future patch.
Mimiron will sometimes spray the room with his P3W X2 ability in phase 4.
UPDATE: We've hotfixed a solution that will prevent the ugly mass death, but there is still a minor visual anomaly that we'll fix in a later patch.
Mimiron's Aerial Command Unit can sometimes switch targets from the normal ranged tank to a different target in phase 4.
This behavior can be caused by the ranged tank moving outside the range of the Plasma Ball ability, which is 30 yards. We'll update this in a future patch to create a phase 4 version of the spell with a longer range. The current spell has the shorter range to allow the ranged tank to move the Command Unit more easily in Phase 3.
Mimiron's Assault Bots corpses don't despawn after phase 3 ends, and they can hide mines with their bodies.
We're going to have them vaporize after phase 3 in a future patch.
Some of the XT-002 Deconstructor adds can evade.
We're investigating these reports.
The Ominous Clouds surrounding Sara can sometimes be triggered even if a player does not enter the Cloud.
We're investigating this issue currently.
Crusher Tentacles in the Yogg-Saron encounter can sometimes have an incorrect number of Diminish Power.
UPDATE: This has been hotfixed.
Saronite Vapors in the General Vezax encounter sometimes do not provide mana properly.
We've noticed this and are looking into a solution.
The above isn't the total list of all issues we're checking out and fixing, some are visual only or are very rare.
