What do housing aficianados think of the Brightness setting?
On the one hand, whoa! Some powerful new ways to change up your castle look by dimming decorations, even able to better match color schemes if used right.
On the other hand, it will automatically mess up certain decorations when using advanced movement (even just selecting advanced movement). The giant purple gems lose their transparency, the orange gems immediately spew heavy smoke, and ornaments lose their color. Sure, those are bugs, but there are so many house decorations in the game, there's gonna be a lot of wonky.
My advice to you guys is before you select an item for advanced settings, make sure to place a second item of the same type and test it first. I had some items already placed and then selected advanced movement, and I basically destroyed them and I had to take them out (by destroyed, I mean I put them in a permanent visual anomaly state, and I couldn't clear it or put them back in place).
