After several battles, I noticed that it doesn't seem to be applying. I've been playing the same map against the AI for many days. I've been constantly reloading saves.
In the turn-based mode (on the map), the hero's luck stat shows 6 or higher. When a battle starts, my luck stat is 0.
Before this, I was playing normally for days, and suddenly this bug appeared. Unfortunately, restarting the game didn't help.
Any ideas what might be causing this and how to fix it?
