I'm the original creator of the boxshu.tbm mod, and based on my own and others' input, I created some slightly altered .tbm-s of the main variants which should eliminate:
- The "your feet is stuck in the ceiling" glitch
- Accidentally dq-ing yourself by somehow touching the outside of the dojo.

The mods:
-boxshu_fixed.tbm
-boxshu_mushu_v3.tbm
-boxshu_esport_fixed.tbm

If you see unsolved bugs or issues, feel free to let me know.
Enjoy!
