HoMM3 HD bug reports.

Today, we're already playing with the second opponent, and we're having trouble with the timer (we set it to chess mode). It constantly "jumps," sometimes showing 1000+ hours, and other times reducing the time. When making a move on the map, it shows one time, but when entering a battle, it changes it, but not by a minute and a half, but by 20-30 minutes:(
Has anyone else encountered this?
