Another player had "privatized" the output chests in the Public, XP spawner on Normal @ 9, , 588. I'd appreciate it if those could be re-released to me so I can make them public again, thanks. GranDan68
I was able to re-register them, set protection back to "Public", and reconnect the hoppers! Thanks Unfortunately, the OP sword went missing in the process, so I had to make another one Fellow players, please let me know if the farm is not working as expected.
