Units won't show up in the Army Cores tab of the campaign screen. For example, cheat-nuke the first Morning Sun scenario after purchasing few units to see nothing in the tabs. Same problem also exists for custom campaigns.
The transition of core units between campaigns still seem to work though.

I don't seem to have any valid core-saves from the past left, so can't test if they still import correctly.

I had that same problem till I clicked the gray boxes in the upper left hand corner of the Forces area and they came all right into view. I just finished the Marine campaign with no problems at all.

Strange, I don't see any unit in the campaign screen, no matter what campaign and which filter box I check or not in whatever tab. Without showing units, there is no export-saving possibility. At least someone else playing a custom campaign has the same problem like me. That's with v.3.4.0 at least.
