Might as well spam this exploit since NK has effectively abandoned the game and made it hilariously easy to make lots of city cash with replaying special missions. :P
You don't need to resort to the power exploit anymore because starting in an update, you can place infinite windmills and watermills (starting at level 35), however it can help level you up faster.
Here's a list for the City Cash per 1 XP ratio:
Windmill: 3000 Cash / 120XP = 25 Cash / XP
Watermill: 3250 Cash / 125XP = 26 Cash / XP
Monkey Bank Lv. 2: 7750 Cash / 200XP = 38.75 Cash / XP
Monkey Bank Lv. 3: 37750 Cash / 600XP = 62.9167 Cash / XP
Monkey Bank Lv. 4: 97750 Cash / 1600XP = 61.0938 Cash / XP
Banana Farm Lv. 2: 22000 Cash / 250XP = 88 Cash / XP
On a time basis, here's a list of the amount of XP per minute:
Windmill: 120XP / 510 minutes = 0.2353 XP / min
Watermill: 125XP / 510 minutes = 0.2353 XP / min
Monkey Bank Lv. 2: 200XP / 270 minutes = 0.7407 XP / min
Monkey Bank Lv. 3: 600XP / 1230 minutes = 0.4878 XP / min
Monkey Bank Lv. 4: 1600XP / 3390 minutes = 0.4720 XP / min
Banana Farm Lv. 2: 240XP / 960 minutes = 0.25 XP / min
In short, doing this exploit with windmills and watermills is the best way to save money, however upgrading banks to level 2 and then demolishing them actually gives you XP faster. Only use this method if you have a shitload of leftover cash handy that you can't do anything else with, which let's be real, you will if you are farming the consecrated ground mission over and over again. xD
Keep in mind that the building's base XP is discounted because that's the XP you lose when demolishing. The upgraded XP is kept.
This DOES NOT WORK on the Flash version of the game as demolitions work as intended there.
