I recall that I saw the post, had an example in-game and took a peek. I didn't test. Did anyone else?
I didn't test per say, but Miri's oil fields start out with many damaged oil points. So obviously I need supply to get the repairs done. Through experience it was obvious that the supply unloading was not being assisted by the NS available. My fix was simply to move ops to Brunei. From there the supply was unloaded in a day, and moved easily to Miri, which had the demand. Unfortunately this is not possible in every occurrence. Nor is it truly a test.
