Posts from Bug: infinite enemy turn.

I created a map for Heroes 3. I started testing it, and it turned out that a bug occurs. During the opponent's turn, the game freezes. The opponent cannot end their turn.
What could be causing this?
I suspect it might be due to the large number of objects on the map. I added too many free monsters to the map, or maybe there's just too much of something else?
What generally causes this kind of bug?

Moreover, if I use a cheat code to reveal the entire map, the "infinite opponent turn" bug happens as early as the second week. But if I don't use the cheat, this bug happens much later.
The map size is 144x144.
It's a two-level map.
I'm using HD Mod 3.665.

If needed, I decided to create a map based on my literary work. By the way, could this also be the cause of the bug: maybe there's too much text in the map?

Most likely, the problem will disappear if you install the HD mod, the latest, 5th version, and it is also recommended to install the SOD_SP plugin and enable the "HD+" option. This eliminates almost all known bugs in the game (but you still need to configure the SOD_SP settings).
The amount of text on the map should not affect the gameplay. However, if you open the entire map using a cheat code (even better, record a video of the AI's actions after that), you can see which player and at what moment the game freezes. It seems that this may be related to the AI heroes having too large an army.

Yes, the AI can have an angel alliance, and that can cause freezes.
Try the latest version of the HD mod, as already suggested, and if that doesn't help, you can attach the map.
