I’ve started a Minecraft server with my friends on a 1.16.5 paper server and pleas planning to build a mob farm. I’ve done a ton of mob farms so I did one myself but some of the water dispensers (only some) would dispens out the water just like the others but not take it back. The dispensers that didn’t take up the water are in the middle and everything else worked fine. I’ve noticed quite a lot lag surrounding water and sometimes ladders. With the ladders you sometimes can’t climb them so you have to disconnect, refresh and reconnect. With the water it’s like if you are on solid ground and can run as always but if your head is below the water the player will still need air. Another bug about the water is that often when you place it it immediately despawns and often when I pick it up it doesn’t get picked up. I changed from paper to spigot but nothing changed PLEASE HELP
