Random Movement under water

[przemratajczak]

MaNGOS: 9272

Any creature with InhabitType = 2 and MovementType = 1 are falling on the bottom.

how to reproduce:

1) spawn creature

insert into creature values
('9000006','25203','571','1','1','0','0','4569.34','6325.88','-47.3439','4.84171','300','20','0','9291','0','0','1');

2) make it use InhabitType = 2

UPDATE creature_template SET InhabitType = 2 WHERE entry = 25203;

look what happens.

I tried creature_addon MONSTER_MOVE_UNK13 nor MONSTER_MOVE_FLY was working. Sometimes update is not sent to player that creature remain in original spawn point but players can see it at the bootom or in different place
