The problem is with cartography villager when its about to release the woodland explorer map

when so happens the server gets a big amount of lag that may cause it to crash

I tried that on singular player and that also caused a lot of lag but the pc handled it after 1 min but it heated a lot

I knew this bug of an online server I was playing on, it crashed every time I try to get a woodland explorer map and I tried that on other servers as well and it did cause them to crash and they didn't crash only once but after 5 min of complete lag the villager revealed the trade
