Just checked again, vanilla world, no addins, no experimental settings (I specifically checked the village trade balance).

Also updated to 1.20.41

Still happening. The colours seem to revert back to normal at either chunk reload or night/day cycle.

+1

This is new in this release v.1.20.40

See screenshots. 

Also note - this is not an imported world; it's a regular save.

If I play for a few minutes - the blue goes away.

Large village at Y=64; trigger a raid; since the last major update the raiders spawn in closed caves that are not surface accessible. Previously they spawned at surface level.

I've had to hunt all of the caves under the village and build access to them :\ Not a great experience.
