Base not registering supplies sold on to it

[Snozzz]

Yes
solved it
turns out that it had been given BA at some point and under the default setting allowed more
as it bought the BA no one noticed they were doing it wrong
lesson learned. deliberately set BA not to buy
thanks

Edit
close inspection suggests that it was infact supplied with RA
but tallied it as BA
to explain
2 bases where being supplied, exports and imports, by the same person
exports recieved RA x2 loads (BA was already blocked)
imports recieved BA x4 loads (BA may or may not have previously been introduced to the base, but unlikely as not needed)
i dont think anyone managed to get it that wrong so specificaly
having set to block BA now hopefully this cannot happen anymore
