Shortly before christmas I had no problem with the embark command in relation to a mission I've built that relied on the embarkment of troops for mission progress. A week back I tried to mission again with some friends and at that point the ground troops just stood frozen next to the helicopter and didn't embark.
I solved the problem with creating a trigger zone that simple deactivates the troops instead, but it seems that this command has stopped working once more... Would be nice to see it fixed... :thumbup:
