It seems very difficult if not impossible at times to get CW resources in particular to flow well. For example in a game we have N Atl convoys down to 8 and a line fun through Denmark strait in MJ 41 yet the entire line through US East Coast, Canadian Coast, Denmark Strait, and FG is ignored by the game.
Also the game insists on sending a saved BP from Liverpool to China instead of a BP from Calcutta factory.
If the game could just stop trying to flow resources and give an option to let players decide manually how resources flow then keep that setting that the player makes it'd be a huge help. I don't mind manually setting path for any resource then saving that path - that would be preferable to the current nightmare that is production planning for CW. Game tries to be smart but it's dumb....and I know the game theoretically has functionality to manually set resource flow but then the game just overrides what the player sets anyway....trying to be smart.
Anyway here is what seems like a clear bug. The 2 oil resources that were flowing from SU to GE as part of trade agreement pre-war can't be used by SU in MJ 41 even though GE broke the pact and DOW'ed in MA 41. I doubt these will ever be use-able. Here is screenshot, and file.
