Issue Description: I have gone from having the map rendered in "Hires" to have it in "Lowres" because it occupied too much space, when I deleted the data and rendered again the map did not work, I have the modified worlds.txt and I suppose that the previous configuration that I had was not adequate for the resolution of "Lowres", so I tried to remove functions of the worlds. txt until it worked again and the problem is the "extrazoomout: 3" by removing that option I got the web map working again (it didn't load before going from "Hires to Lowres with the data deleted even and rendering again), so I guess there must be some problem there.

on Spigot 1.17.1 using the latest dynmap this works fine. could be your unsupported build is messing with the settings, we can only support paper, spigot, forge and fabric.
