Bugreporter reporting in. Chapter Seven and thats where things get sad. Captain Ironside does not switch sides after declaring to fight for Gardon. Some of his forces do, but the buildings and most the army still remains hostile. Instead of reviving Larine the exale - ranger, the altar tooltip says "Larine the exile - Larine the exile". Same for Cora, Brian and Gardon, so I assume this is a common bug in the demo. Chapter 8: In case if you join the mages be careful - your golems' immolation affects them

Hell, that happens even during the cinematic, im pretty sure ive kill a firemage or two. And as for things
@renegade said: the Cora/Scarlett choice is not removed, it is remade as far as I understand. As for knights in chapters 4 and 6 - I just dont understand why are we given knights in the first place. We cannot build them anyway. Think they should be replaced with respective units we're able to build for a particular chapter. Summoning Zed is also not a bug, but rather an easy way to get him into the mission I guess. Will report more later.
P.S. Larine scene made me sad. Wish I could choose Golden Guard version of chapter 14, but i guess its not done yet

UPDATE: Chapter 9: unable to finish the sidequest because there is no "invest 10k lumber" button in the marketplace. Albeit I bought an amulet of spellshield and staff of negation, shouldnt complaining, right? Chapter 11 (Gardon scenario): I think the ending cinematic is bugged. First of all, Renauld's body disappears, although it'd better if the body remained there. Secondly, there is a missing dialogue bit between Gardon and Marin. Marin says, that he has no choice but to tell Gardon how the cannon works, and then Gardon says "I accept your terms, I dont wanna see his rotten face". I guess it is implied that Marin asks for Renaulds body, but that part of the dialogue is missing. Also Gardon executing Lerrig scene is missing. Chapter 12 (Gardon Scenario): I guess the heroes have Vail's leadership boni pre-researched?. Chapter 14: The ending cinematic shows nothing but a black screen. The dialogues are in tact tho. The rest seemed in a working condition to me, except for the ending itself, but I guess the story is far from over, isn it? I'll make another run in a few days to make sure I havent missed anything.
