Allow your spouse to actually access the door and the path way to the house.

[Hanzonekage]

Sometimes when i pay attention to my npc spouse, i notice them phasing through the walls into conplete darkness. I suggest allowing them to actually access the door and out of the house to town when they buy groceries. Like they can use the door before marriage but why cant they after? Its a bit weird but its not a big problem.

I agree with you on this

It happened to me a couple times in the past


It would be nice if they could fix this problem in the upcoming update

Just saying

You should report this in another section:

Suggestion section is for new features.

These are two seperate things, the phasing issue is a current bug, probably to do with the way that the npcs are navigating placed objects

Many spouses if not all do in fact use the door, they'll walk right out on days when they head to town to work or hang with the villagers. They don't walk onto the farm (just walk out the door and teleport to the entry of the bus stop) because then they could possibly break items and potentially make the same bug with them phasing out of the house happen on the farm map if that issue was changed, overall not worth the effort to see the spouse walk 10 extra meters.
