HoMM3 HD is a mod (add-on) for the game Heroes of Might and Magic 3.

now the heroes keep crashing. I don't know what to do, I've gotten used to its interface, but it's really annoying in online mode.

What to do – don't stay silent, but immediately report such issues. I haven't tested it on the international versions for a while. The sooner you report a bug, the sooner it will be fixed. Which is logical, actually. If it crashes with an error message, you should send me the text; this will greatly help with fixing it and speed up the process.

I played in a friendly offline mini-tournament on Buka-Sode with versions 2.94 and pre2.95 – there were no crashes or glitches.

I'll test it online on the international complete version now...
