1.2.1 installed. First mission of the Hammer Campaign. What I do is Start Mission, take off from Batumi Base. Gain altitude (15.000feet) and go straight to target. I use CBU 97, HOF 3000k. I release the bomb and the time begin to coun. When time reach 0 suddenly game crashes to desktop and campaign finishes there. It happened to me twice. Any other had this problem. Is it a known bug?
