The answer is aggressive stock buyback thanks! The miscellaneous expense went to 89k one month at that AI company. It's a 3% fee for stock buyback 89/3*100=$3,566k which was the decrease in cash I was seeing.
Thank you for the map editor suggestion. The map editor is less intimidating than I anticipated. I think next testing should be what changes to the map editor fix this issue. Map settings of note on the africa map: no assuming chairmanship, there is limited track building, computer ai is conservative in track expansion and aggressive in payout/stock buyback. The default having aggressive payout/stock buyback in computer ai makes this scenario much easier than Heartland.

Compare to in December when profits that year are 1,757k and annual cash flow due to dividend is -137k (most likely the dividend from dec hasn't been issued, so real amount might be around -120k)
