Here's an example of a sacrifice setup at City rank 40, done for each temple.
#Bloon beacon mistake free
Feel free to sacrifice 1-2 ice towers if you want a little more, but the Absolute Zero ability is very useful so make sure you have more than 4 remaining.

Good candidates are Bombs, (Mortars can stun MOABs with the Pop and Awe ability, although not quite powerful) Boomerangs, (Handles ceramics well, but Temples can already shred them easily.) Apprentices, (Pheonix is dull, period.) and Glue (They can't do anything against MOAB). Knowing that, we want to sacrifice towers that are useless to an end-game CT setup. Moreover, because of the fact that unlike in btd6, temples will still consume slots of the towers sacrificed, we have to be very careful about what towers to sacrifice. This will likely mean you can't reach that glorious 30k sacs with every temple.

In BMC, you have a limited amount of towers to work with, and even when sacrificed to a temple, they still eat up a slot placed. You may already know that you must sacrifice 30k of Explosive (Bomb Tower/Mortar), Apprentice, Glue, Ice, and Miscellaneous towers to have the max amount of sacrifices, but this can get tricky in BMC. The big bulk of effective temple usage is sacrificing towers in it. So we're going to have to turn to alternative sources of cash, those that aren't round dependant. Now that we have our farms setup, there's now an immediate issue to address: Farms lose value the longer we go into CT, because there are a fixed amount of cash that can be gathered from them each round. Continue to repeat this until you have 1 farm left, as thanks to, once again, monkey knowledge, having a single bank will give us a percentage of our current reserves every round, which can quickly spiral.
#Bloon beacon mistake upgrade
After placing 4 farms and upgrading them all to 2-0, upgrade one to 3-0, then when you get around $6k, sell the other 2-0 farms and upgrade your 3-0 to 4-0, then to 4-2. So 1-2 Bloonjitzus and a Cluster Bomb should be enough on most maps, or Destroyers on water tiles. While you could start bloon trapping right now, it's not required as until ceramics come, your towers will likely pop the bloons before they enter the trap. While you continue to place down 2-0 farms, (they are quite efficient, especially with monkey knowledge) there is a definite need for some additional defense.

With your first bit of money, start with a 2-0 farm, and your free dart and random tower. You'll want to use Farms and other sources of income to bring in enough cash to afford a solid defense late game. This may be obvious to some, but the golden rule to winning CT is to plan for the late game. If you have already entered CT with this bug, there is no choice but to brave the CT or wait until a new CT milestone appears. Capture some additional tiles before entering CT to fix this bug. If you enter CT directly after completing a Bloon Beacon tile, the double waves of the bloon beacon will carry into CT. WARNING Contested Territories are currently (and maybe will be forever) bugged.
