Thanks. Messing with the distribution fixed the problem and I got the troops to embark successfully. I ran into the same apparent bug that you did, however, following the drop off. After landing and disembarking its troops at a FARP, the Mi-8 ignored its flight plan, returned to base, and then proceeded to start its flight plan from scratch only without landing at the FARP this time. Also, the troops I landed refused to follow their next order, which was to advance into the nearby town. Instead, they just chilled at the FARP for the rest of the mission. Probably all WIP stuff, but if anybody knows any hacks to get around this problem that would be great.
