Guild Wars 2

Just finished the event after the patch and the fix.
Claw still heals to full hp on 2nd phase.
Then it seems like it is not taking damage.
After 10 to 15 min,it’s hp suddenly drop from 100% to 20%.
Then it continues on to not take damage.
Then again sudden drop to 1% before it is finally killed.

Seems to be some weird “lag” regarding hp bars. It happens with mobs (hp bar freezes when not apparently yet depleted, but the mob dies normally), blooms in TA (making really hard to go through some parts, as you can’t be sure if the thing is going to blow on your face or not)… even world bosses. Behemoth seems to spawn at 90% of hp, then regain up to 100% when it becomes targetable.
Many people (including myself) have started to notice all this recently… say one or two patches ago. So it may be related.

HP lag for world bosses, could be ?!
Noticed two weird things twice now with the Jungle Worm in Caledon.
When it spawned it had 50-60% HP, then suddenly 100%
Slowly it kept loosing HP while being attackted, and then at something like 10% HP it suddenly dropped dead.

I also noticed sometimes with normal foes they drop dead when their HP bar is not fully empty yet.

Happens with Shatterer as well, he spawns with hp bar around 80% (at least today on Underworld it did)
