New Geologist/Explorer That Brings Refills

So i've been looking at christmas event and seems you guys at BB do enjoy giving us specialists... albeit not very useful ones :) Still not complaining they might be good for someone.

But that got me thinking, for a future event, why not introduce a new geologist that brings refills for our mines, i think that might not be too dificult to implement or adapt even with the current skills.

Or if is too dificult to implement on a geologist how about an explorer, that would bring refills. I think that is a specialist that would be of use to many.

He can bring all types of refills with different % chance acordingly to value, say copper would have 10% chance omniseeds 2% for example.

Anyway just a thought, might not even be that great of an idea.
