PeeeBeee

Got back into the campaign after the last update, had to restart Adapt, which is fine, to be expected. Stuck on Supply Network. I get up to leave the staging area point just fine, get the task to set up for the ambush and then nothing happens. I usually set up in Nagales, but I have tried other places too. I've restarted the mission at least ten times. The only time I've seen the next part of the mission trigger was once when after waiting more than 15 minutes, I made a suicide run into the town west of Nagales with the off-road to be taken out by one of the APCs. A second or two before that happened the autosave and next scripted event triggered. Another time, as soon as my radio briefing on convoy ambush finished, the spotters all called in progress reports instantly and the helicopter spawned. Anyone got any ideas? Is there some way to force the next scripted event to trigger?
