Observed behaviour

When casting containment on players in Multiplayer. It would fling them a few blocks away and trap them somewhere else until the effect wears off. With Mobs, it would just loop the sound of when you touch the barrier and it wouldn't really trap them. This also happens in Singleplayer. When using /effect [PLAYER NAME] it would keep them in their current position. (I tested this bug without any addons as well and the issue still occurs)

Expected behaviour

Well, for players to be in their current location when being cast upon.

Steps to reproduce

1. Get the spell "Containment"
2. Place it within a wand.
3. Cast it on any Player or Mob.
