Necromancers – “The Bait” [Campaign 3, Mission 1]

Please help! I'm sneaking past the patrols and successfully reaching Isabel... she's negotiating with Markel... and it seems like the mission should end, but NO!!! The game continues, and I don't understand why: I've tried capturing the castle in the dungeon, then approaching Isabel, I've tried not capturing it and going straight to her - it's all useless!!! The game saves itself before the conversation with her... we talk, and the game continues??!! I initially had an unlicensed version... I thought it was a bug, so I bought a licensed version... but it's the same: the mission doesn't end! Maybe someone can suggest how to complete it correctly? (By the way, I'm using Artmoney, could it be affecting it?):smile32: :confused:
