    I have run into a bug where the long range troops will lose the ability to shoot, and other non shooting troops will show Shots = 0.
    This is on the latest version of Heroes 3.5 gaming build, with the latest Advanced Classes Mod and latest Third Upgrade Mod.
    This has happened on previous versions with these mods also.
    It happens during online multiplayer games when a computer player attacks and kills any of my player heros. Immediately after that, the ranged abilities of all my shooting troops is gone, and some of the non ranged troops will show 0 shots, and none of them can shoot.
    The other player’s troops will still be normal, possibly because they have not been attacked yet by a computer player. I haven’t played it out yet to see if the same thing happens when the other player loses a hero to a computer.
    Each time I’ve seen this, I had third level upgraded troops, happening with different towns.
    I hope that explains it well enough.
    Thanks for the outstanding work on this awesome game.
    Is the Heroes theme the Russian National Anthem, much like the StarCraft Terran theme is the Korean National Anthem?

      Hi Grant, this looks like a more complex problem, but it’s not recommended to have a script “Troop stacks gain experience” enabled when playing online, especially with AC mod.

      Try playing without this modification to see if the problem recurs.

    I played Shadow of Death campaigns with Third Upgrades Mode v2.8.7 but the heroes’ experiences, skills and levels are not carried over to the next scenario. The heroes are reset to level 1 with default skills at the beginning of each new scenario.

    I dont use any other mods, except some default ones like WoG Animated, ERA scripts ENG, and WoG Scripts.

    Does anyone know how to fix this? Thanks

      Hi Snow, the worst thing you can do is play campaigns in the WoG/ERA environment 🙂

      And this is the result. Campaigns are specific, and all possible scripts can spoil them. Try Safe Sod modification:

        Thanks Liso1,

        I just want to re-live the old days with the stories in the campaign with new perspective ^_^.
