I recently started playing this map, but due to the bugs, especially when playing with HD+, I almost gave up at the very beginning.
I played until the point where you first have to run away from the guy with 300 angels, and then kill him. Since I was used to playing with HD+ and SoD_SP, this guy simply disappeared in the place where his army was supposed to undergo some kind of metamorphosis. I, of course, assumed that this was intentional, especially since at the beginning of the game, the woman with the golden dragon disappeared in the same way.
However, considering that there was a pillar nearby that opens after killing this guy, I started to have doubts about this disappearance. And then I started making fruitless attempts to kill him "as is". I won't lie, I didn't spend too much time figuring out this battle, but I tried attacking him with the entire army, hypnotizing the fanatic, and looking for landscapes that would be advantageous to me. No luck. I could only kill about a hundred angels.
Okay, I left everything as it was and continued playing. That is, I let this guy disappear, assuming that he had fled from some battle and might come from the other side of the pillar. I played for a few more weeks, mainly with the woman and Mutare Drake on the Necropolis location, but then I couldn't stand it anymore and decided to see what was going on (even though I really don't like watching or reading walkthroughs for maps that I'm going to play). I opened the first walkthrough I found on YouTube, watched that part, and realized that I wouldn't have the mental strength to continue playing with such tricks. First, I would have to replay a significant portion of the game for the 100500th time, which I was already tired of, and second, if I continue playing with HD+, it's obvious that such bugs could occur absolutely anywhere. And playing without HD+ and SoD_SP is already unusual. Maybe I'll finish this map someday (I saved a few of the last saves), but for now, I've given up.
By the way, I also left the Necromancer with thousands of dragons, and it seems that this was also wrong. And there's another funny moment: if you play with HD+ and on the first day you stand on the portal so that the woman with the golden dragon doesn't pass, and on the second day you leave 2700 skeletons in the captured castle, placing the Necromancer with dragons next to the portal, then the woman with Armageddon, when she comes out of the portal, easily destroys the thousands of dragons, but she can't kill the 2700 skeletons in the castle and dies at that castle. The pillar, accordingly, remains unopened. I'm not an expert in Heroes mechanics, but it seems strange that 2000+ dragons die from her Armageddon, but 2000+ skeletons don't die in the next battle. It seems that something is related to experience overflow?
