I hope someone can help...I'm on the Eastern Front having been promoted out of Stalingrad. Presently trying to secure a German tank repair facility. I've cleared the ground level, basement level and tank workshop but am still being told to secure the facility. There appears to be a second floor above the repair shop but I can't find an access point. I've been back upstairs, outside and searched every room; I can even see Russian troops outside the workshop but I can't get to them either. Any suggestion?
