Can confirm that it happens in 1.16.1. Using an R7 1700X and RX 5500XT and my FPS was cut in half with about fifty signs in one area, some with text, some without (water elevator). FPS boosted back to nominal levels.
OP, I'm having an issue where villagers REFUSE to find a new bed, and have decided that the player beds will be their beds. That means that I have what I call the "wall gang" stuck to the walls of my house getting themselves killed at night and never going to bed.
I assume this is due to the hierarchical issues where villagers cannot independently select a bed for themselves based upon their ability to pathfind to it?
The bug has been partially fixed. While animals will now jump over a block when you are luring them, they will immediately "lose interest" and stop following you. In the end, I just decided to use the lead I had cheated in last update. ¯_(ツ)_/¯
Still an issue in version 1.16.2.
