This is rediculous. I had exactly the same problem. Did all side missions, captured all 4 villages and had no way to end the mission (this is after a couple of days to play). So i try Endmission cheat, but it meant the next mission is unplayable. So i have to revert back to badlands and start again...
The fact that i cant even revert back to my own savegame (after taking 2 towns and the first side mission completed , about to assault the 3rd town) and have to start from scratch if most angering. This is not the first mission ive had trouble with, almost all bugs in other missions described on these forums (e.g manhatten) have also happened at some point.
BIS, I am angered and dissapointed to play a campaign so riddled with bugs. Despite the tactical freedom compared to the original OFP which i have been a fan of since its release, i dont remember ANY bugs in the original campaign. Dissapointed customer, may wait for Codemasters effort.
