Geologist doesn't find marble in sector 1.

It started today. The geologist doesn't find any marble in sector 1 and this is seriously crippling my marble production.

Yes, I know there is only one of the two that can be active at a time, but right now I have zero.
Yes, I tried refreshing with no sucess.

EDIT:

Someone in help channel finally found the problem. It is possible to place a building that is in the way of one of the deposits. If this happens, it will refuse to discover any of the two spots there.
