Regarding your comment,I tried to repro this issue on dedicated server with friends.
But I finally found that this issue occurs only on singleplayer/editor.
Sorry for confusing,this could be trivial if not untrue.

I hope there would be reloading feature for CSWs but this is not scope of this ticket.

Thank you again for researching and separating your time.

Thank you for reviewing Iceman.
I always appreciate your support for community and I wish this ticket would be something positive information for A3's weapon system.

I uploaded a mission for reproduction.
In this mission,2 ordinate AI have their backpacks.

I assume you succeeded to assemble usable CSW because units given their backpacks when they were player character.
But in some cases on MP,some playable units would be still AI when it get backpack and later players join these AI as JIP(Join in progress).

Or just that the black dot is the first one would help a lot.

This is a kind of incrementalism.
Drawing a line,or even curved one must be further useful and appropriate for this splendid game!
