Ranger - "Higher Vampire" [5th Campaign, 5th Mission]

I haven't seen anything like this before. I captured all the castles except the southernmost one, found the Tear of Ashera, and Nicholas holed up in that castle and won't come out, even though he had 1,000 dragons by that time!!! So I thought I'd gather some troops and give him a hard time. I gathered troops, but it backfired when I brought my hero to see how many troops he had amassed, and I saw that he had 126,000 dragons! I was shocked. While I was standing nearby, a thousand dragons joined him every day. I'm shocked. What kind of glitch is this?? Does anyone know?:confused:

I'm tired of it. Kind people, can someone share a save file from before the battle when you defeated Nicholas? So I can defeat him and calm down, please.
