To trigger the bug you must set up a 'buy deal' from another city and accept it. (part of monthly expenses)
1. You have a buy deal set up. You *cannot* already have the resource in your city.
2. Reopen the deals tab, select sell to the city that needs water.
3. Cancel the buy deal and
4. Reselect the sell deal in the same budget session
Make as much money as you need, the amount you get is based on the amount of the resource your selling. Don't forget to cancel the deal before you exit or it may bankrupt the city you are selling to.
buying water from City 2
sell water to city 3
cancel buy deal, re-select sell deal
the amount you get will depend on the quantity of the resource, and may cancel itself after a few months, but you can repeat the process.
This bug allows you to get unlimited money and works in any version. There is no download required. If you have problems getting the bug to work, leave a comment below.
If you get a glitch where you have unlimited demand for water, cancel all water deals and save then exit your city. Reload your city and build water pumps to reset demand to correct levels.
