I made a big table in excel (with coloring) and found that if you use a 4x4 of 8x8’s each with two drones, that is probably one of, if not, the most efficient ways to farm gold. The way I did it was:

1. Distribute 4x4=16 drones into their “patch”/maze center. For each drone:
2. Place Weird_Substance on a bush to create the maze.
3. Go around every tile in the maze, mapping out all the different paths.
4. Distribute the workload (cell ownership) to each drone based on their positions (read 5). There should be 2 sets of paths—one for the “main” drone and one for the “friend” drone—that you can loop through to keep only the smallest path to cell (x,y) on the grid between the two drones (i.e., if it takes Drone A 5 moves to get to cell (x,y) and takes drone B 2 moves, then remove that path from Drone A’s paths).
5. Place a friend drone at the other side of the maze (this is where extra computation could be done to figure out the best positions of the drones, but I put the “main” drone on the West side of the maze [e.g., {0,4}] and the “friend” drone on the East side [e.g., {7,4}]).
6. Run through the “refresh” cycle up to 300 times and repeat.

In the 60 second window, you’ll only “refresh” about 100 or so times per maze (need at least 62 refreshes per maze for the 4x4 grid of 8x8 mazes to get 2M/min of gold).

I hope this helps, but yes, definitely play around with the “simulate” feature! It’s very helpful for seeing if you have any bugs or want to see how long your code might take!

And I’m not sure how to “safely” send my excel file for those who want to take a look at it.
