Mongoose glitch

In Forge mode on any level grab a Mongoose and take it close to a(n) (invisible) barrier. Have someone get on and then a second person get on passenger. Have the driver get off but the passenger stay on. Have another person go into Forge mode, pick up the Mongoose, and by using RT and the left stick push the Mongoose outside of the map. The passenger can then get off and he will be outside of the map. As this is one of the simpler methods to get outside a map, it is also the most command means of exploration outside the boundaries.
