MonsieurDeteste

Hello there I was just about to play the 'Red Revolution' Soviet campaign (no.11, the one where you have to defeat Yuri in Moskau). Immediately after starting this campaign something EXTREMELY odd happens: I'm about to set up the first power plant or barrakcs, sending out some tanks... No matter what I do I get immediatley DESTROYED (Zofia says: "Unit lost"). All my troops and buildings are just blown away within a second and "Mission failed" occurs on the display. I have absolultely NO IDEA what am I doing wrong or what it could be since I couldn't find any hints of a RA2 campaign with a bug like this? It must be a bug, right? What can I do??? --> recorded screen https://youtu.be/g2IAHAMkeJM
