Cannot complete alpha 11

[Palmaroma]

So I made the mistake of saving with 23 minutes left, on mission 11 of the alpha campaign. Well aside from that mistake I still get through the level, destroy all scavenger bases, and send a bombard team to kill all enemy units on the ramp area and cause the important artifacts to drop. So no enemy unit is left and I advance past the choke point with about 8 minutes left. A transport suddenly appears on the enemy lz, then bolts off without picking up any enemies and once the transport is gone I get a "mission failed" message. Is this a new bug in the latest iteration of Warzone 2100? I was damn sure every enemy was dead, and I certainly saw no enemy being picked up, what is going on here?

Forget the bombards and the scavs. You must be quick to kill the heavy cannon tank. Then go to the base and destroy the enemy-units. Thats all. Then you have time to make some fun for experience with the scavs. I will show you tommorow the way. It is even the same question for this mission. It is a very hard mission-but you can find the answers for your questions in this forum. Don`t be lazy to search
