HoMM3 HD bug reports.

Indeed, there is a problem. I finally figured out what it is. In the latest HD version, build 3.811, version 4, the multiplayer is not compatible with previous versions. If you play 3.811 build 4 vs 3.811 build 4, everything is fine, but if you play against earlier versions, both will receive incorrect data from each other. I will release a fixed version within the next 24 hours.
