Ok, so there's this glitch that can make you fly. Follow these steps:
1. Go to your estate and stand on any fishing dock.
2. Click CANCEL, then turn around.
3. Fall backwards and click ESC while falling. DON'T CLOSE BOOK OR THIS WONT WORK!!
4. Go to Map and click ' Back to Playground '
5. Run right after you click back to playground. AND VOILA!
This works and it's pretty cool. If you tp to somebody who's doing the out of house glitch, it's pretty cool. Bored... so I just posted this. xD
