Well mate, i have the same problem! I have posted my problem in the Technical Subforum, but no response, i included screenshots i am positive we have the same problem. I have to say 1C is a joke, i am very sad i paid 50$ for the game, even more sad that i recommended it to another 5 people so 6 of us bought it off this website and its been weeks, no help. I have finished the SP 2 times already.
Well its a hard choice today, West (good supported but unrealistic games) or East (bad support but realistic) improvement is nowhere in sight...
