I think the paths should either go through the icebergs or don't be there at all.
Why is this a bug?
But it seems like it introduced a new performance issue along with the bug fix: https://youtu.be/H8PZgqm7fGc?t=678

In my previous comment (link to comment) I linked to a video showing this bug happening. From what I can see neither A nor B is the reason that this is happening.
Also in 1.16.5
Indeed not fixed in 21w03a: Ilmango's snapshot video
1.16.5 also

I have the exact same thing, literally hundreds of warnings. (1.16.5)
I just tested it again on a fully vanilla server and now the bug doesn't occur any more. Sorry for not testing on vanilla before posting here.
I use version 1.16.5 and still experience this bug
Had the same issue myself on a server on my own pc. (1.16.4)
This happened to me also. I run a BDS on my pc. And now I upgraded from 1.17 to 1.18 the skeleton spawner is empty (it wasn't when I discovered it in 1.17).
I can provide the world if needed.
