Hey, hopefully someone can help, or maybe I just can't find the new thread.
3 Quarries have disappeared.
1) Always in twilight forest. (so far)
2) Yes the quarry was placed outside of the marked area.
3) The third time I did it, I had cleared area before placing the quarry, and when I came back, the hill had refilled where the quarry had been. Only the quarry, redstone battery, ender chest and the nearest few blocks of the frame are gone, the rest of the frame is intact and will not degrade.
4) I have had it happen with markers and without.
The only thing I can come up with is that I have been logging in from a second location, kicking myself offline (Different computer in a different building, same account) from the first location that I left running.
Thanks for any help.
