Steps to reproduce:
1) Enable output log
2) Find terrain alongside the outer world border where the blocks at z/x coordinate 29999999 have a higher y level than blocks at 30000000+
3) Ender pearl towards the 30000000+ blocks, you will then be constantly moving back and forth inside the block at 29999999 and 30000000
4) Check output log to see the spammed "<Player> moved wrongly"

similar problem to MC-251684 but I'm reporting about console spam
