Unfortunately earlier today, a player named Swosher got on the server and undertook a quite intense and thorough attempt to grief as much as possible in the overworld and the cleanroom. Unfortunately for him and fortunately for us, we have block logging. Everything has been rolled back to its previous state (to around 5 pm CST) and Swosher was banned. There was a brief hiccup that caused Guardians to be unable to ban players, but that has been resolved. Thank you very much to @d0ct0rwh00ves for her help throughout managing the issue.
If you see anything out of place, please let me know and I'll fix whatever's broken, but the rollback was thorough, so everything should be back to usual.
Cheers everyone, and thank you for your support!
