First ，I love Dawn of War III ，the game is excellent in battle.But because of bugs ，exps of my elites are fixed ，I can't gain any exp by any kinds of pve .So my elites upgrade slowly.it's true.
hope you fix the bug.
By PvE do you mean campaign or comp stomp? You have to make sure you are "playing online" vs a computer to get exp.
Of course I were playing online.The problem is my exp bars are fixed.I can get exp,but my exp bars didnt grow and elites cant level up.
