Yep it is..... It seems that Biome dictates its facing the wrong way.. & Thats what I thought lol... Cos when facing north its south & sometimes other if in the waste biome, & in the wilderness they face west or east ....I assume it's wilderness poi's that are not facing the right way.
I haven't tested it recently but I think they always spawn facing the same way and don't consider the road at all.
Also gup, I thought it was if you face south (in game) then you will see the front door if said door is placed on the north/top of the prefab and it has no rotation applied?
