HoMM3 HD bug reports.

Hey guys. Lately, when I play through a VPN, at a certain point, the game starts lagging terribly, and my entire computer freezes (in the browser, it becomes impossible to do anything or launch anything else). I think it's because of the color scheme changing. Is it just me?

And am I in the right forum? Added. It's just that I have a new and powerful computer, but the game freezes, and everything freezes with it. Plus, this happened in a 2v2 game, and Misha said he sometimes has a similar problem.
