Epic War Age (EWA) - Adapted Mod Collection

1. I encountered an issue where, when adding my modification, the hero's skill tree, stats, and so on change, but the creatures remain the same. When attempting to remove the NCF file from the data, the game launches but doesn't progress beyond the main menu. What's the problem?
2. I also couldn't figure out the hero description mod – where are their skills located in the folder?
Thank you in advance.
No longer relevant. I've already figured it out.
