when trying to do an infinite emerald loop with cartogrophers i discovered that in multiplayer the trade wont go bellow 4 glass panes, but when i do it in a singleplayer world it lowers down to 1 glass pane with no problem. i am playing on a server but i am fairly certain that there arent any modifications that are causing this seeing as i know exactly what plugins & datapacks are there

so my conclusion is that i belive that there is a bug with villagers on multiplayer servers
