[Reaper]

Reaper: That may have several causes,
1) x/y coordinates set wrong, so it appears somewhere off-screen
2) action: set incorrectly, so a wrong frame is spawned (perhaps one without anything)
3) Maybe the object limit is reached in-game
4) Perhaps no opoint_end? (Or would that cause an error, not sure.)

While all of those are possible, I was thinking of something different. Everything inside the opoint: is set correctly and the move never works, no matter where or when I try it.
