The bug
Upon unlocking a trade for an explorer map by leveling up a cartographer villager, the server is able to freeze while searching for the next ocean monument or woodland mansion.
To reproduce
Create a new world
Spawn in a villager
Place a cartography table
Trade with the villager
❌ The server might freeze while the villager is leveling up
This is easier to reproduce in custom buffet worlds.
Original description
If I level up the cartographer villager beyond apprentice all entities freeze , also one trade is missing (the map which has the monument , mostly because I don't have any monuments in my buffet world )
If i start a regular world and go to trade with a cartographer the missing trade appears

I just reproduced this in 15.2, so maybe the bug resurfaced?
This is from the Log and chat window from the server; I had quickly leveled a pair of cartographers.

Confirmed. The duration of the freeze depends on how far away the next ocean monument / woodland mansion is.
Edit: And yes, if no monuments can exist in your world, the trade won't show up. For the same reason, you cannot get any explorer maps in normal flatland worlds. That's probably working as intended.
