Groundhog Mines

The Groundhog Mines were an ore farm located below the Trading Hell that used a bug which may or may not be. It was named after Groundhog Day, a movie in which the main character experiences the same day over and over. Similarly, the two chunks in which the farm was located reset to a previous state every time the server was restarted, such as every day at 11AM (Europe/Berlin time).

History
The bug was noticed by on 2014, who subsequently started building the farm with help from  and.

The farm could only be used once, as it was discovered on the day after it was set up that the reason for chunks resetting was two of the testificates in the Trading Hell which had corrupted trades. One of the testificates was killed by in an attempt to farm the soul sand which is part of the Trading Hell, and the other was moved to a different chunk by  and  as part of an experiment, and vanished (because the chunk where it was previously located could be saved again, but the chunk it was moved to could not).
