NHF – new heroes for Heroes V 3.1.

Is that the same hero?

Yep, that's him. Also, the Necropolis player who uses Earth magic to reduce damage before the battle isn't working.

Is that the same hero?

I found the problem. I have an external hard drive connected, and it was trying to load the game from there instead of the computer. Now everything is working fine.
BUT now, for some reason, every hero on every map refuses to engage in battle... [profanity].
