Giant snakes always falling through ground

Official server PVE-F#2 bot hthe huge serpents I found so far falls through the floor when killed.

The one next to the bonedragon in that pit. center of the desert.
And the one in a “dungeon” south-west of the unnamed city.

Both of them were killed 2 times now and all 4 cases they instantly fell through the floor.
BTW nice job making it attacking inwards really nice touch.
