Question about the map "Empire of the World".

A hellish map. Not in terms of difficulty, but in terms of how tedious it is to play. It's not a strategy game; it's one long quest, and a very monotonous one at that. Everything boils down to finding a hidden passage, an artifact, or an event. There's nothing else interesting on this map. The battles, especially after obtaining the vulnerability medal, are nothing but a yawn-inducing experience.
P.S. Regarding the game freezing, starting at a certain point. This isn't a bug in the map itself, but in the game's heroes. On practically any map where there are legions of troops and the game has been running for more than 10-15 months, you can encounter this. Without going into the reasons, I found a solution. Using a debugger, it's easy to see that the program enters an infinite loop in two places when the game freezes. If you 'nop' the conditional jumps that are used to exit the loop at that moment, the subsequent execution proceeds without any visible issues. In any case, I haven't noticed any deviations in the gameplay. You can, of course, patch the executable file on the disk in advance, but I prefer to patch only the memory when the game freezes.
