Navmesh holes when using changing "cell swizzle" & tilemap orientation

[zxubian]

Steps to reproduce:

• add a Grid
• set swizzle to XZY
• Add 2 tilemaps to the grid
  • make one the ground, adding navmesh modifier and overriding the area to "walkable"
  • make the other one the walls, adding navmesh modifier and overriding the area to "unwalkable"
  • set both tilemaps' orientation to xz
• add a NavmeshSurface2D to an empty object
• set up the agent size etc
• bake

Issues:

• while the navmesh is correct for the indoor walls, there's a gap between the indoor area and the outdoor area, disallowing agents to enter/exit the building (see first image below)

The issue does not appear when the swizzle & tilemap orientation settings are left at their defaults. (see image below)

Specs:

• Unity 2020.2.1f1
• NavMeshPlus: latest (from Git)

Hello,

I have tried couple of scenes from https://github.com/h8man/RedHotSweetPepper and didn't find any artifacts when swizzle set to XZY and tilemap to xz.

Does NavMsehSurface2d - Advanced - Default Area set to Walkable?
