P.P.S. I tested it some more. My previous comment wasn't entirely accurate. On relatively small maps, the mod does work and makes the gameplay slightly more diverse. (However, on a small map, I didn't have enough time to fully appreciate its significance compared to the base game).
But!
However, on large maps, problems start to arise. The point is that I tested the mod on a very large map with 8 players. And if it doesn't crash at all on a small map, regardless of the time played, then it seems that on large maps, the mod is no longer handled properly. I decided to point this out in case anyone decides to try it. Any improved ARMG is better than the standard one!
