Alright, so I overcame the issues with #B07 by using the alternative attack profile with SAMP-250s instead of Belougas.
However, I've just done #B09, the LGB strike, and, probably because of changes to DCS's fusing and arming windows, the laser code is not set correctly on mission start. Its on the default 1688 instead of the 1588 the drone is using. This could be fixed either by just briefing it or updating the default in the mission editor.
Great campaign otherwise, I'm having a good time!
