Ok, so for me it seems to be a problem with how many units are placed on a map manually by me. If I only place the players squad and the helicopter insertion module, then heli insertion works as intended. It's only when I start to introduce lots of units that are manually placed by me, and synced to the ALiVE profile module, that I have problems.
I assume it's because my system has low RAM and processing speeds, and simply isn't loading things quick enough - and so for whatever reason, vehicles that aren't synced to the ALiVE module are spawned at the lower left corner of the map (co-ordinates = 0,0,0 or NULL). The result is a large explosion as all the vehicles are spawned on top of each other.

TL;DR: I need moar power, my problem is not a bug that needs fixing.

Is there a fix for this yet? Been having the same problem, also using RHS, and also on the Takistan map.
