If you are sneaking, and sit in one spot for a little while to wait for the right moment to move, followers will get bored and start to sandbox around the area. Potentially blowing your cover.
This is because there is no check for sneaking on the sandboxing package. By adding a condition of (PlayerRef [PLYR:00000014]).IsSneaking = 0 to the COM_CND_PACK_SandboxWhileFollowingPlayer CNDF (0028BF2C), we can prevent this from happening.
By checking PlayerRef instead of Subject, sneaking will also cancel any ongoing sandboxing, on top of preventing new sandboxing.
