Entered the twilight forest with said magic map, in hopes of finding more structures.

Main points: the error happened when I joined the server, meaning it's likely the error happens only when the map is in the player inventory. As for the source: https://github.com/TeamTwilight/twilightforest/blob/1.20.x/src/main/java/twilightforest/network/MagicMapPacket.java#L48. Level is null, so it throws, but because it fails, it never gets a chance to update again.
