When I spawn in the Tardis Rewrite, Doors shows an error message in the console saying "tried to call method 'GetExit' a nil value" and it says the error is on line 61 of the lua code. The error makes the entrance to the Tardis invisible. When I open the doors, all I can see is the inside of the exterior model, and when I walk through I enter the actual interior. When I turn around to look back out, I see the portion of the skybox the interior spawned in rather than where the exterior is pointing. I tried disabling all my addons, redownloading doors and Tardis Rewrite, and clearing all parts of both addons from my Garry's Mod addons folder. Am I missing anything? Help would be very much appreciated.
