Buying the last item in a warehouse does not properly transfer ownership

If someone buys all the rest of the last item in a warehouse, it does not appear to properly transfer the ownership. Two examples that happened today:

  • I bought all the grapes that someone else had listed in my warehouse in MBPV, leaving the warehouse empty. However, someone else (belonging to “Express Flight Regional”) was able to load my grapes onto their plane and fly them away. The grapes are still listed in my own “Owned Commodities” but they are loaded on a plane that does not belong to me.
  • Someone else bought all the fertilizer in my MBPV warehouse, again leaving it empty. I got paid for the fertilizer according to my Income page, but the fertilizer is still listed in my “Owned Commodities” page with the same number of units as before.
