When I first discovered the issue, it was almost an hour later into playing the game - during the "final production planning phase".
Japan was still missing its controlled oil production resources on the production screen during this phase.
So I reported the issue here.
Now I just tried to replay the game turn a second time, but farther forward into the future as Bommerrang suggested.
I just found out that the controlled oil resources do return to Japan's production screen - They are recounted right after Japan spends its build points later on in the production phase.
So I guess they do come back later on.
I am not so sure now that this is a bug, but maybe the production planning interface screen could be improved to avoid the confusion.
Internally, the program marks oil resources and saved oil points as 'Used' when they are consumed during the Use Oil Reorganization phase. Any oil that has been Used does not appear on the Production Planning form. At the start of the next turn, all the oil resources are internally marked as 'available', so they "come back" in future turns.
I prefer the processing the way it is. If the used oil points showed up on the Production Planning form, players would want to save them or send them to some factory for production. It is cleaner to simply remove them for the form - since they have been consumed entirely for the turn.
Note that if you use less than 0.5 of an oil point to reorganize units, it will not be marked as 'Used' and you will still have it to either save or send to production. But those are the WIF rules - not my doing.
Perfection is an elusive goal.
