Ok that was a pain...
Sold data from the DW2 trip - 36 pages takes a long time to work through. 1.2BCr - and I sold loads outbound when we built Explorer's Anchorage.
You can see why they feel the need to do some rebalancing as you can earn that very quickly by mining compared to months of surveying and mapping.
I do wonder exactly how they'll "balance"exploration...
