Pirates of the Wild Sea – “King of the Wild Sea” [Campaign 8, Mission 2]

Maybe it shouldn't be related to the Conflux? Does this mean the game is unplayable because of the bugs? At first, I played with this childish Conflux, and in the very first campaign, the game glitched; summoning a dark elemental cost about 1000 mana, which simply wasn't available, and the stat-boosting items didn't work for Anastasia. I completed the campaign entirely with Ludmila. I started over without the Conflux and completed all the main campaigns; there were no major glitches. But now, on this mission, it's happening again, even without connecting to the Conflux...
I still have Shades of Darkness and two campaigns left to complete...
If anyone wants the game disc, I can give it away, or the account. Maybe someone who hasn't played it will be able to complete it... Just say the word, and I'll give you the login, password, and game code.
