By the way, for some reason, in Xiedu, whether with the SOD_SP plugin or without it, the hero would get wiped out by an event with 300 angels and couldn't complete the game until I watched a YouTube video to figure out what was going on. And, by the way, in Lord of the Rings, I never needed Hitran, which is not the case for Xiedu.

By the way, I also left a Necromancer with thousands of dragons, and it seems that was also a mistake. And there's another interesting point: if you play with HD+ and on the first day, you stand on the portal to prevent the woman with the golden dragon from passing through, 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 emerges from the portal, easily wipes out 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 to be related to experience overflow?
