Lending BP problems

[TeaLeaf]

NovDec 1940 France has promised the CW 6 BP, which has set up 6 convoys in the Bay of Biscay.
The BP are not being sent. Production planning shows France keeps the 6 BP for itself. No sign of any trade there.

Latest version is played, hotseat.
Paris just fell but AFAIK, this should not be ending the agreement (?).
SepOct this agreement was fulfilled just fine. I am sure I did not acciddentally tick the one time only box when making the agreement.

EZOCS are not a problem for at least 5 of the 6 BP France is still making (should be transported without a problem from factory to Brest and Bordeaux).
Am I missing a rule or is this a bug?

Maybe part of the problem: the game assigns 'save-locations' (in my game, other than Brest/Bordeaux) for the 'to be generated BP's for trade'.
AFAIK the player cannot specify where the temporary storage location should be for such BP's,
so perhaps this goes wrong if the game 'stores' them at a location that becomes cut off (or even taken) later (Paris/Rouen for example)?

I can ofc attach a savefile if needed.

Could you post the gamesave? That makes things easier to check...

Sure, take a look!
I have zipped that save for this [8D].

Hmmm. Not what I was hoping for. This is a bug and needs to be put on the task list... Thanks for finding it.
