Today both my jolly geologist and a normal geologist reset their search time for gold ore.
With my jolly geologist I thought it simply had frozen or gotten stuck or something when I noticed it. The 2nd time it happened with my normal geologist I knew it was at like 2:54 hours out of 4:00 hours. When I log back in again now it's at 3:57 hours.
This hasn't happened to me before as far as I'm aware of.
