Base 1124 Urumchi - it has 50 oil but only 20 refineries. This must be a mistake - every single base in the game has the same amount of refineries as oil.
Um, often true but there are quite a number of bases where the oil and refineries don't match. Goes both ways, sometimes more oil than refineries and sometimes more refineries than oil (look at Tokyo )
Oh, I never played the Japanese (Allied fanboy here, hahaha). On the Allied side every single base has the oil # matching the refinery #, so any excess oil cannot be refined anywhere else (given that no refineries will be available).
Unless, of course, some oil wells are damaged somewhere, and you put Urumchi's extra oil on a boat and send it there for the now idle refineries. As Urumchi is in the middle of nowhere (it is close to Nepal), that might be difficult... hahaha... so I think it is a mistake.
ps: Urumchi is actually farther away than Nepal, oh no!! It is almost in Siberia...
Actually a few bases on the Allied side have more refinery space than oil, such as Melbourne and Sydney.
