HoMM3 HD bug reports.

This is a standard Heroes of Might and Magic synchronization issue. HD isn't the problem here. And since no one is working on Heroes of Might and Magic III 3.58 anymore...

How can I check the version of Heroes of Might and Magic? I think I just have the first version/standard "In the Wake of Gods." I think there are some like that :D

It should work in battles with neutral creatures, although I haven't tested it with PvP.

Honestly, it doesn't work in any battle. And if you check the box in the options for "Fast Battle," it doesn't become faster.

And in general, PvP shouldn't work in Heroes of Might and Magic.

It does work! But it's a bit buggy.
