This is working as intended:
[media]This could be because of slow ram speeds, or slow disk speeds.
This issue could be caused due to world lag. (Such as hundreds of entities in a single area.)
This could be because of invalid data, which is unlikely.
Any other reason...
Did you notice any strange behavior in 1.19.XX stable?
I can confirm this when I fill over a certain proximity.
I think it is actually supposed to mean how many more skins there are:
Minecraft shows the first 5 skins in the pack, then says how many more there are.
+In this case, those could only have 5 skins, showing 0 means 5 >+0< =5. So, this could just be a confusing point.
It still does it
1.19.11
I have attached a video.
please mind the framerate, I'm playing on a less than minimum spec pc.
Can confirm, it is the incorrect resolution when hovered.
