I didn't make it!
In the mission where you have to clear out the apartment buildings on the Russian campaign, you have an objective where you blow up the Panzer II tank. So I do that. Thing is the objective star is still there though I destroyed the tank already and my next objective doesn't appear. I have a few mod IWD files in my CoD2 folder. Deleted them to see they fixed the problem but to my disappointment nothing happened. I don't know what to do and I really want to complete the Russian campaign.
