Lighting and Partitions.

[Zigabar]

I've never noticed the lighting like OP's before and now I'm afraid to go look...><

This, and that partitions don't change with the rest of the wallpaper, are probably two of the biggest pet peeves I've got about housing.

This is exactly why I try to use half partitions and glitch the wall planters to sit on and hang over them instead of full partitions or I stick with the default walls if it can't be avoided. I can't stand the brown walls clashing with the wallpaper.
