That's something new.
Why would App.ET_START_WARP be called when you stop warp?
App.ET_EXITED_SET I can come in, but I limit the effect from leaving the WarpSet.
It's possible that the warping is taken over (it's something I would like to do one day, maybe), and that the warp set is used, somewhere along the road.
But that still shouldn't matter. Since only 1 sequence is allowed at a time.
