it looks like the mod was deleted, i also can't find it

Its patchlog on google docs is gone too. Links to the steam workshop page are dead, so it definitly isnt accessable anymore here.

"From now on, vehicles will be included in their proper modules — for example, the Predator in Angels of Death and the Leman Russ in Hammer of the Imperium! Important change: You no longer need Imperial Vehicles of GrimWorld to build vehicles. Now, you only need the faction module (like Angels of Death or Hammer of the Imperium) and Vehicle Framework. Simple and clean!"

Thanks
