Recommended:
Use the attached mission,
extract 'teamswitch_analysis.Stratis'
copy it into '.../[user]/documents/Arma 3 Alpha/missions' (or equal)
load 'teamswitch_analysis' in editor and PREVIEW it.
Alternatively:
Place a group of playable units on Stratis. (I used: Teamleader, Marksman, Medic, AT, Automatic)
Click PREVIEW.
Teamswitch to every unit using teamswitch dialogue.
Switch back to Teamleader and move at least ten meters to a significant location (=a rock, a concrete wall, a car, whatever).
Switch to every unit one after another and gather the units near the teamleader.

If you don't notice anything unusual, repeat these steps within the same session and try to reproduce them as fast as you can. It might help to accelerate the time to double or times four - probably because of increased workload for your CPU.
