I play on hard mode, so after 5 hours killing the Purity in Old Haalyash. I see in the questtree, that i have the choice betwenn killing Merelith or invoke a titan, but i don't have plans for the titans. But after killing Mereltih and seeing my mother i get the quest "Forgotten Knowledge". That seems wrong to me So if i don't want to kill Merelith i have to do this 5 hours again.
So my question is wouldn't it be better, if the quest trigger for the quest "Forgotten Knowledge", start's when i do the optional quest seeing your mother's body?

I don't know if it is a bug or not, but if the "Torch of the Bane" are throwing torches at any of my infatry or cavalary, they just do nothing and get killed. Only the Rangers notice them. If I want to kill them, with infatry or cavalry i have to click on every one of them.

After a savegame has been loaded, i have to enable Economy View again and disable Tutorial again. Loading a savegame takes a very long time.
