Heads up:
My new gold geologist from the event wiped out/replaced one of my industrial gold mines on my arch. The indy gold mine had at least 4-5k+ gold ore in it and it was definitely turned off/sleeping.
I suspect it was the gold geo's 'refill' skill replaced the indy gold mine. Lost an indy mine and all of the gold ore in it. The gold deposit even has the gold wreath/leaves around it and shows the gold geo's influence/bonus' on the deposit, so I know it was her that did it.

EDIT: As a further note to detail, I have not put any training or skills on the geo yet.
