Recommendation: Explorer Deposits

Hi,

I'm not sure if this has been suggested before, but I think it would be better if a notification was given that the maximum number of explored deposits has been found BEFORE sending an explorer out. It sucks getting a message an hour or longer later that says you have too many of a certain deposit.

Just a suggestion.

Cheers!

That would close a loophole letting us search for a deposit before we should (if there is one exhausted deposit -- you can send out 4 geologists to find them -- and if 3 more deposits expire before the geologists finish their searches, they will all be found).
