Currently only Movetypes L and S are working (Land and Sea), it would be nice to have that Movetype A (Air) working too for example flying birds etc.

Yest it'll be nice, but have you ever seen something like this on other shards? OSI?

True, it would look like a npc perma. walking at Z:= * or maybe we could specify our z? this way it could be half-flyring like a ghost? some ideas lol
