Ok, sure some have seen this around lately, figured out how to do it
1. Go to open a stand (Living>Action>Stand)
2. Set stand to a quickslot (Right click on Coin image and will go into quickslot)
3. Set your active and go to Fight Mode
4. Rapidly hit Tab and the quickslot for stand
5. It will either open like normal, glitch standing in peace mode, or glitch standing in fight mode
6. Pick one and laugh
