Problem occurs when I edit Mt.Komorebi lot

After I hit the lot edit option while my sim has reached the peak of Mt.Komorebi,

I always end up being stuck in endless loading screen when trying to return home (or just simply trying to leave the lot to anywhere) + when trying to save the game load.

I don't even have to make any changes to the lot. If I press "Edit lot" button and makes no changes (add nothing to lot). The problem still occurs.
