Update on Asharu: It got hit by another trade disruption for supplies, and I sold the stockpile of 100,000 supplies I previously bought from them at 1 credit. While I made a generous profit in credits, I did not get as much experience as before, only about 400,000 experience, less than what I got the first time around. I wonder if the game remembers when the commodities are spawned and grants XP based on when they were first bought (but not re-bought). Also sold about 100,000+ more supplies stockpiled at Jangala. When it was over, I had about 200,000 supplies to buy back at 1 credit each. While I do not expect huge experience rewards next time, it is a guaranteed cash cow that keeps getting bigger after each trade disruption.
Also, Tibicena was hit by supplies shortage, and I sold much, somewhere between 40,000 to 100,000. Unlike Asharu, bottom price was 90 credits instead of 100, and when the disruption was over, Tibicena had much less supply overstock than in Asharu. I bought back the overstock, but it was less than expected.
