No relief on treasure map or explorer maps

I'm not exactly sure what you mean by "reliefs", what is that?

A screenshot of the issue would help 🙂

Relief (French for "the highlighted") or* georelief* is understood in geology and geography to mean the surface shape of the earth, i.e. H. the shape of the terrain, which can be described with various parameters (especially the absolute and relative heights as well as the slopes and distances between the individual shapes). The relief is created by the action of internal (endogenous) and external (exogenous) forces on the earth.

The picture left is about version 1.17 and the picture right is about version 1.18 rc3

Weirdly enough these maps have relief, when you play survival in multiplayer. Not sure, but when I found one, it had relief.

Can confirm in 1.18.1. Just to make it crystal clear, this can only be reproduced some of the time and not all the time.

Noticed this issue in 1.20.2 pre-1.

Buried Treasure Map 1 (no relief; map is centered at [64, 64]):

/execute in minecraft:overworld run tp @s -74 54 -173 0 90

Buried Treasure Map 2 (works as expected; map is centered at [-448, 320]):

/execute in minecraft:overworld run tp @s -778 48 486 0 90

(Dunno if the maps' coordinates make a difference, but I included them just in case)

Still present in 1.20.2 rc-1.

Still present in 24w12a.

Still present in 1.21 pre-3.

Still present in 1.21.2 rc-1. Likely related to MC-263100.
