Aurum Vale instance, multiple bugs.

Time and Date: 3rd March 10-10:30 pm
World: Lich
Character Name: Sarak Malkovik
Instance: Aurum Vale

Attempting to run the instance "Aurum Vale" and met with various bug. High level of lag, with the healer not being able to "connect" with any healing spells (spells were being cast but not registering the healing effect).
Summoners DoTs being cast but not registering on the targets multiple times consistently.
When interacting with the morbol fruits at the Locksmith boss, all characters were frozen in place for 10-15 seconds, without the interaction indicator meter ever appearing. The fruit would be consumed, but then characters would be frozen to the spot for another 5 seconds or more.
Generally unplayable due to severe lag and non-responsive interactive items.
All the above was experienced by all 4 players within the instance, at the same time.

Exactly the same on Cerberus at approx 20.00 GMT yesterday in Arum Vale

I can confirm this - AV has been buggy for some time now and I have tested that the problems arise only in that instance because i did AV with a mix of HM and EM primals and other dungeons. Every time I went to AV I had problems, whereas in other instances I did not have any problems.

Problems with AV:
*skills don't register (even though CD's go off)
*interaction with objects (fruits) are slow on first boss - you need to press several times and it takes at least 5-10 seconds for the press to register.

Usually i experience this starting boss 1 up to boss 2. After boss 2 and during boss 3 the encounters seem smoother.

I can confirm this same thing happened for my whole team on Phoenix yesterday around 9:00pm GMT and the day before at approximately the same time. We've so far not been able to complete it because our tank lags so much and his combo's don't work correctly, sometimes he uses a buff and it doesn't actually go off but goes on cooldown, and he has a hard time dodging anything. These problems occur on the first boss but are so bad by the second it's basically unplayable for him. Also our healer disconnects at various times throughout, and myself and the other DPS have very bad lag issues as well. Never had this problem with the same party on any other dungeon thus far. I also had a strange issue in the AV yesterday where no matter how many times I cast a song it never worked.

Confirmed on Ragnarok, i wrote a thread too some days ago, is there any chance that they will fix it?
