This is a persistent issue for us which I've only seen mentioned once on the forums 2 days ago, no idea how to reproduce on a different system seeing as we are running a fresh install. - Install server from steam
- Use arma3server.exe as headless client
- Load any mission on tanoa with headless client
- Headless client will slot itself in lobby and on mission screen
- Load mission and headless client will deslot.
