Recently, status depths have randomly had a different skybox (like an indoor version of Jigsaw Valley's skybox) and played the construct music instead of the status music. Most of the status depths still have their usual music and skybox, but the "new" version appears like 25% of the time.
(The screenshots are a few patches old, but it still happens in the latest patch)

^I don't think you read those parts, because that is obviously a bug.
I've read it, and I've seen similar instances occur on shock levels.
Then I still think it's a bug, but it effects any status depth rather than just fire. I'll edit the title and OP.
This happens with every type of level that used the old status backgrounds. I don't think its a bug.
