Just noticed that my despawn sphere doesn't show through colored glass. I don't know if its a spected behavior.

It's not intended, but it's also very difficult to fix these translucent rendering render order things. "The easy fix" is just swapping the order in which these render in relation to vanilla blocks, but that just swaps which thing you can't see through the other thing. I'll look into it at some point later on, but I also need to learn a bunch more rendering stuff to properly understand if there is a way to fix this "nicely".
