New theory: slimes spawn somewhere over 32 blocks away from the player but still Despawn randomly at over 32 blocks (slimes only spawn if I get really far away but despawn if I go back) so you have to get really lucky to catch one before it despawns. That is why they seem so rare.
Big news, a whole ONE slime spawned in version 1.0.8 guarantee you that I will never get another one. At least I know that my slime chunks are actually slime chunks and that slimes spawning at a WAYNE lower rate than expexted.
The chunks themselves are fine just the y coordinate determines the glitch within those chunks
Nevermind when I approach the cube the glitch happens again what is happening
The same thing has also happened to me after upgrading to 1.0.7 on one of my superlative worlds
Interesting, thank you for the confirmation.
I downloaded it and it still does not work
