Report of all bugs in Ulduar

Hello everyone.
Since I didn't see any post telling about it, I decided to report here all bugs we found I and a friend in our favorite raid instance : Ulduar. We know that nothing has been done since 2010 but we have still hope to see those bugs getting fixed on live realms.
The Siege of Ulduar :
-Since 4.2, mechanical spiders and Helicopters driven by mechanical gnomes are no longer attacking players like before.
-Brann Bronzebeard is no longer telling players about the power of the four towers before Flame Leviathan when they got close to those towers.
-The two spots before Formation Grounds are no longer repairing vehicules like before. You have to make your vehicule go on it, leave the vehicule, let it got repaired and then go on it again, instead of just stepping on it like before to have your vehicule repaired.
Ignis, Razorscale, XT-002 Deconstructor and their trashes semm to be all right.
The Antechamber of Ulduar:
-We noticed a strange bug on the Iron Council when Brundir is the last member alive. When he is casting Lightning Trendils, he sometimes is not flying but just got fixed on the ground like on this screenshot :http://imageshack.us/photo/my-images/826/z04f.jpg/
Kologarn, Auriaya and their trashes seem to be all right.
The Keepers of Ulduar:
-Hodir's chests sometimes are unlootable for no reason.
-You sometimes can access General Vezax and Yogg-Saron while Thorim is still corrupted.
-Ironbranch's Iron roots are bugged: When getting destroyed, they are still fixing players and doing damage on them. To get free, players have to die or to use immunities.
-For no reason, Freya's chest is not spawning at the end of the fight. This bug has been reported a lot of time since Cataclysm is out and it happened to me a lot of time when I started to solo her early in Cataclysm.
-Freya's animation when she is casting Ground Tremor is a wrong one. She is like punching the ground instead of casting a spell as you can see on this screenshot :http://imageshack.us/photo/my-images/28/i9hb.jpg/
-Mimiron's creations HP are bugged since 5.0.4. For exemple :
Before 5.0.4 , in 25 Hardmode : 8.7M , 8.7M and 5.8M.
After 5.0.4 : 15M, 15M and 10M
-The melee damage of the Leviathan part are anormally high, pretty much the melee damage of Arthas in heroic 25 man.
-Rocket Missiles of phase 2 and 4 are visually bugged. They seem to fall quickly on the ground but they are falling in reality like after their nerf. This bug killed me the first time I encountered it :D
The Descent into Madness:
-For some reason, General Vezax and his trashes sometimes are not spawning.
-Some classes have a lot of trouble on General Vezax because they cannot regen their mana like before, like my friend who are a paladin.
-Yogg-Saron death animation is bugged. Instead of dying, he just freezes on place like on this screenshot:http://imageshack.us/photo/my-images/7/adoe.jpg/
-In 25 man, Sara's Psychosis is making player's sanity falling under the 30 mark , making the sanity a huge problem when they are only a few players fighting against Yogg-Saron.
The Celestial Planetarium:
Finally here we are, the boss that I and my friend are considering as the most awesome boss in the game. We put a lot of efforts to find all the bugs that are affecting Algalon the Observer.
-Celestial Planetarium contours were a lot more detailed in Wotlk time, as you can see in these screenshots :
Before :http://imageshack.us/photo/my-images/571/49c3.jpg/
Now :http://imageshack.us/photo/my-images/41/sq24.jpg/
-We noticed a strange thing with Brann's speech when players open the Celestial Planetarium's door. In Wotlk, Brann was walking until the entrance of the Planetarium, then was beginning his speech. Now, he walks until the platform where the battle against Algalon will proceed.
-This is the bug reported since its apparition during the 4.0.3. Since this patch, the platform is no longer getting translucid and pretty much is making the impression of "Universe" dissapear from the fight. It is also causing Cosmic smashes, stars and Algalon himself to sometimes become invisible: http://imageshack.us/photo/my-images/16/j9af.jpg/
-Since 5.0.4, Algalon's Big Bang has no longer a visual of ... hum ... Big Bang?
Before 5.0.4:http://imageshack.us/photo/my-images/826/jc77.jpg/
After 5.0.4:http://imageshack.us/photo/my-images/199/b2ak.jpg/

I guess this is it. We perfectly know that Blizzard has a lot of important things to do before that but one day, Ulduar and all other instances should be fixed to allow all new players to fully enjoy all of them. May all of you have a nice day on Wow!

Thanks in advance for reading.
