Can we get an advanced player to do further testing and research,
Oh the terrible memories this brings me.
I have experienced this. It may be the resolution of your monitor. I believe that to a point antialiasing will improve the graphics of the game. After that point, your monitor cannot display any higher resolution and it only strains the performance of your computer.
this happened to me too. I had a goat in a boat for the achievement because I was waiting for the notification, thinking "how could I possibly mess this up?" I left only to come back and find the goat missing. My villagers fortunately have survived several recent updates and are still around, having no nametags.
Tridents thrown by the player will also despawn 😞
NOT FIXED IN 1.17.1
