I have a different variation of the same glitch. My villagers have the default unemployed texture even though they have a job (I'm also on Nintendo switch version 1.19.20)
Same here on same new version. Game will freeze when autosave occurs and during autosave game will drop in performance for a bit.
I've had a similar issue with this as well, instead of playing multiplayer I was playing single player on bedrock Nintendo switch version. The autosave will result in a decrease in performance sometimes and also can sometimes freeze the game for about 10-50 seconds. They said it was fixed in 1.18.31 but its not. (my version is 1.18.31)
This happens to me too, the llamas will turn green and red and the villagers will have the unemployed skin with the job badge. Horses are also pitch black and I think the tropical fish are also having issues but I may be wrong. I'm on latest version minecraft 1.19.20 and I play on the latest software version of Nintendo Switch.
I tested it on other platforms and its only Nintendo switch. I also tested it on all my worlds created a new world and the glitch is still present.
