You may have a low difficulty. The skeletons are less accurate in Peaceful/Easy than Normal/Hard/Hardcore.
Same here, except it only happens on one specific world for me. My survival world. And I can’t even save because that crashes.
I seem to be mistaken. It is not survival worlds. It is my world which is corrupted somehow. If anyone has any solutions please help.
Something similar happens to me. I’m playing on Switch and after 1.12.1 whenever I load up my world within ~a minute it always crashes. It seems to only happen in survival and not creative, as I went on my creative world without issue.
You might have downloaded a Java Edition shader by mistake.
