If a turret has no stabilisation, either set in config with stabilizedInAxes = 0; or with the enableGunStabilization script command, it is forced into a stabilizedInAxes = 3; state when turned out in a turret with isPersonTurret = 1 set.

In the repro example mission attached the slammer tank has had its stabilisation disabled with the enableGunStablization script command, but again this occurs with config set examples too.

Repro instructions:

1. You will already be turned out and the AI is in a loop of turning left and right. Observe the commander machinegun rotating.

2. Turn in and the turret stabilisation stops.

3. Turn out and it's back to being stabilised.

4. tank enablePersonTurret [[0,0], false]; in debug will disable the FFV and the turret will go back to being unstabilised regardless of turned in/out state

Despite the turret itself becoming stabilised, it does not 'stabilise' the FFV unit, so I'm unsure why this is happening.
