My 577.7MB 8-year-old world (previously transferred from legacy console edition and then moved to windows 10 via realms) has a variety of bugs since the 1.18 update, including chunk loading glitches and most notably what appears to be a delay when breaking and placing blocks at times and sometimes not a delay at all but the complete inability to break or place the block at all, audio also not lining up with this at times.
Not sprinting at the right times or sprinting at the wrong times and the icon on the map also being way behind at times.
A delay when dropping and picking up blocks/items at times.
Other bugs also occur, the majority if not all being in some sort of delayed form.
