problem solved all cruisers will lose their weapons in death animation (except vanilla ones they also need new code for disarming their weapons in fuse_li_cruiser.ini and others)
and about scylla bug, they will lose their weapons in 5 seconds though (actually weapons fall off after 1 second)
Murmillo also have this problem because it is using Liberty Dreadnought / Osiris death animation in Shiparch.ini
Change this;
fuse = o_osiris_player_fuse, 0.000000, 1
