Haven't climbed too far down the rabbit hole yet looking for specific cause, figured I'd check if there are any known issues in the mean time.
Having issue where player called logistics helos are not landing to be unloaded/release slung load. They hover in place for a bit and then fly off after a while, as they would do had they landed.
So far I've narrowed down to only happening on dedicated server, regardless of mods, but only in "real mission" conditions. If setting up a very simple single side w/ no opfor mission they will land on dedi server. If running full mission from editor, they also land normally. Running a real mission, even with placement modules to objective only to remove hostile fire from equation, they failed to land. Also of note, called UNITS will land and unload, it's only cargo loads that are afraid of the ground.
Will test more variables, but thanks in advance for any tips or known issue knowledge. :)
