weapondefs_post.lua and map gravity

So the unit rendering position is possibly being delayed a frame? You say that you set it all at once in the same microsecond as creating the unit?

Yeah, that's what seems to be happening, there's a noticeable "flash" from it changing vectors very rapidly. If I could MoveCtrl it before it drew, give it equivalent velocity and vectors, then I'd be all set for transformations on-the-fly.
