We tested the bug after talking with Zapper, found that when picked up the Quarry reset lvl only on ui/storage space but keeps lvl when mining. we were able to take a 17 stone per tick to 27 stone per tick by picking up the quarry and redoing the lvls 4 times. works on all ore types as well. used the same location checking the survey to make sure numbers were not skewed.
Steps to reproduce.
1 place quarry
2 level quarry to max
3 pick up quarry
4 replace quarry
5 level quarry to max
