I finished the map today with archer and Paladin .
I tried to load game with Arren and acher with the code but Arren revived as a 50 lvl hero...
I reloaded with Archer and paladin and load was successfull, both heroes come back with tier 3.
Also when i killed the blue dragon his corpse prevented me from picking up 2 batches of lumber. At the end of the map (when facing Death Knight) i couldnt see anything because of the columns.
I will play this game again just to gather all the potential items hidden in the map. Dagger would be a nice edition to my inventory in order to be able to collect them. I suggest that you change the price to gold as when you have that ammount of lumber to buy it is a much better option to spent it on armor (cause its the best item in the game)
Thats all for now. I hope i was helpfull.
