KNOWN ISSUES:
Helis and possibly other vehicles can explode on entering (workaround - shoot vehicle once to 'initialize' it before entering)
Occasionally when looting items from a corpse, they can disappear. (should be fixed in next Arma 3 patch)
Getting in or out of boats can randomly kill the player
Players cannot hide or configure the HUD (a relog can help, but should be fixed in a future update)
Mission markers not showing for active missions when joining the server
