Main. Replaces the stepping stone with a navmeshed staircase. Added the interior and exterior trapdoors to the navmesh so that followers can detect them properly. If you don't want exterior navmesh edits keep using 1.4. Use only one version.

Use this if you do not want exterior navmesh edits. This does not contain the staircase or follower compatible trapdoor though, they both need the navmesh edit to function properly. Use only one version.
