NHF – new heroes for Heroes V 3.1.

Has anyone played for a long time? Do the hero buffs not disappear?

I tested it for 6 months: everything is fine.
Nimues's upgrades don't match the ones from the original game.
By the way, I noticed a pattern in the game: if one AI captures another AI's castle, it never builds any structures in it.
For Delia, is it enough to replace 0.15 with 15 in NHF_Heroes_percent_spec.lua, and everything will be okay, right?
