The problem is that Jazz can be in various different "states". The state for coming out of a warp is extremely limited... it messes up with stuff like v-poles and wait time sucker tubes, and it doesn't transition well into the injured state. I sincerely doubt UF can do anything about this, as PERSONALITY ASIDE, it would require either recoding the "falling from warp" state or doing something weird like removing the "comes out of warp" part of a warp, which I guess means you'd then fall normally.
