I know my screenshot is in pocket edition but I have this issue when playing Java 1.15.2 on Mac Catalina, I simply don't have access to that computer at the moment and wanted you to see the cell design
I said 2 adjacent 1x3 cells. Make a bed. Place blocks 3 high and 1 wide around the bed with a 1 block space at the foot of the bed so that you have solid blocks around a 1x3 area. When this design is tiled, villagers will teleport into a random adjacent bed
As I said this bug is not invalid, I merely don't have access to a computer to take screenshots at the moment. Please reopen this issue or I will report it again in precisely the same area
