Description:
After his second death, Al'ar in some cases (possible if he died during the phase change) can hang in the air in the center of the room, and it will be impossible to loot him or even select it. In my case, he had 1 hp left, he flew to the center of the room and died there (see screenshots). On the first try, I killed him with the normal attacks of my class without flying, but with .cheat god. I decided to double-check this problem, reset the dungeon timer and beat Al'ar with .damage 50000, and he died as he should: fell to the ground and was available for picking. During the third attempt, I reduced his hp with .damage 50000 to about 10,000, killed him with normal attacks of my class, check his loot but not take that and everything was fine, but when I turned on .gm on, his corpse flew up to the center of the room, as shown in the screenshots, and again became inaccessible to loot and for allocation. During the fourth attempt, I again reduced his hp with .damage 50000 to about 10,000, killed him with the usual attacks of my class, check his loot but not take that and everything was fine, but after 2-3 seconds, his corpse again flew up to the center of the room, as shown in the screenshots, and again became inaccessible for loot and for allocation. .gm on this time I did not enter. On the fifth attempt, everything repeated, but this time I had about 7-10 seconds to loot him before his corpse flew to the center of the room. The server settings are set to Rate.Creature.Elite.WORLDBOSS.HP = 0.1.

Expected behaviour:
After his death, Al'ar should fall to the ground, he should be selected and looted and his corpse should not fly away anywhere and cease to be available for loot.

Steps to reproduce the problem:

1. .character level 70
2. .go xyz 323 15 -1 550
3. .cheat god
4. Kill all trash around
5. Kill Al'ar (twice)
6. If the problem does not appear, then leave this instance, .instance unbind all, and repeat the steps 2,4,5. Repeat until the problem appears.

sounds like the usual bug after the movement rewrite that broke a lot of things and that is still waiting to get fixed

[offl]

It's hard to be sure considering how ancient and wrong that script is

[Ovahlord]

This boss probably has disabled movementflag updating via extra flag since that's a npc with scripted flight mechanics so I assume that it's missing a gravity enable line in his justDied hook.

Disable fly and move Fall on death
