All missions were being resolved except for downed UFO's. Sorry a correction - I could see the Biomass spreading in Eastern Russia/Asia & Africa but it was not yet in my territory. I did play around with it for a bit before going back to an old saved game last night and I was wondering as I had been completing missions a couple of territories away from my existing territory I was wondering if the game was trying to fill in the link between my main batch of territories and where I have been operating.
Kret, No I have not yet seen the biomass and when they are automatically resolved they have only been resolved successfully (ie I get bases from them automatically resolving).
I've had an interesting scenario/bug: After completing the russian base mission, all of the existing missions and any new missions that appear automatically get completed a short time later. Even if a new mission appears and I send the helicopter immediately, the mission gets completed before the helicopter arrives ..... Might have to go back to an old saved game .........
