I just noticed something.. during this episode (When It Rains), when steven is outside the temple, and calling back to Peridot, telling her about the rain outside, "C'mon, Look I'm okay, its just water", you can see that behind and above Peridot is what appears to be roof-slats/boards along with the rafter-beams. However, in the next scene however, you see the rafter-beams.. with no wood slats/boards in-between, only what appears to be rock. I don't know if this classifies as an animation 'goof' or one of those.. differences-in-model from close-up vs far away..
But then you'd see the wooden slats, albeit a bit further up in the following shot.. like.. you'd see empty space between the two in-view.. but above the furthest-up beam, you'd expect to see some slats then.. something doesn't quite 'jive' with the two shots..
It can be argued that the shot is close enough and level enough such that the slats are no longer visible.
When adding errors, we're usually kinda lenient I suppose. If there's like some subjectivity then we tend to avoid adding the error since this kinda stuff happens all the time in animation. Not sure if that makes sense but wat u pointed out looks pretty weird for sure tho
