Quick question

Hello.

Im doing some experimenting with sub crew.
Does anyone know how to delete sub crew models (so that they dont show in the game)?
When i delete data\Submarine\Common\Rooms\Waypoints_Room_CR.chr file, most of the crew is gone but i cant click on crew pictures and assign orders.
Does anyone know how to delete crew models and still be able to assign orders?. (This is just for testing and trying something)

Thanks
