AI cheating on single-player maps.

I managed to create something strange! I and the AI swapped cities and heroes (this happened after loading a save) – I don't know how to post links, so I can't provide proof. By the way, Marmut, my AI also had a flying unit that "took off in a hot air balloon, dropping its army behind." It unexpectedly took off, flew over the water and mountains, and left its entire army behind, meaning all seven types of creatures were left standing in the sea and on the mountains. And it itself was running around without them!!!!!
