I just updated the game with a couple of bugfixes!

The following has been fixed:

• Added slowmotion bind in input options
• Respawn time option now works
• Cannot kick inside vehicles/turrets
• Cannot lean inside vehicles/turrets
• Mouse wheel works for weapon switch (if it's bound in input menu)
• HMG remaining ammo count doesn't bug out when resupplying
• Can hide battalions UI with Home key
• Added alternative flight control preset (the default control layout from beta 5)

If the update isn't automatically downloaded, you can restart steam to force download the update. Let me know if there are any other issues you're running into!
