Yeah, they have moved the bomber behind that building in the most recent patch. Guess they forgot to check campaign impact. Surprised they couldn't have left campaign balance alone while still changing skirmish and MP balance. Starcraft certainly was able to do that.

This might be worth checking, a player made fix:

Hello,

coming to post the same thing

I won the map using orbital abilities: Activate the radar and then detonation and drones, that destroyed the nexus in 2 seconds.

I think the whole campaign should be re-assessed since the latest changes. I'm not sure the maps work as originally intended.

For example in the original campaign (Imminent Crisis), there is one mission where you start in the center with 2 ennemies, 1 substrate top right and 1 dissident PHC in bottom left. The left part of the map is supposed to not be reached by the substrate, but when I played the map recently, it actually did reach it and started building there. That did not prevent winning it, but story wise it is supposed to be exclusive to the PHC dissident.
