There is a problem with ingame progression tracking. I have had game installed before on another PC where I played through the campaign until the end of Orc campaign and now after installing game on another PC, there is no campaign progression and all my previously unlocked icons are locked (surprisingly, even the one I am currently using)
Is there a way to restore my campaign progress?
Hello FrosstEffect,
The campaign progress is saved locally in the documents folder (C:\Users[username]\Documents\Warcraft III\BattleNet[account number]\Campaigns). If you still have access to this other computer, you can just copy/paste the folder to retrieve your progress.
Else, you can restart from scratch and use the super secret cheat “AllYourBaseAreBelongToUs” to instant win your missions. 
Is there any possibility that the game will be more user friendly in this regard, similar to Starcraft Remastered, in forseeable future?
