I won't tell you how to replicate this bug after you knocked me off of that pillar in Jumpchat, Sorry!
anyway jokes aside:
hold control + space + the S key and you'll get stuck about 90% of the time. I was able to do it back to back 3 times in a row. I also reset myself into a normal state by going back and forth from the spirit world
let me know if you can't replicate it and i'll record myself doing it or something
