made a cave map too the dinos on version 1.1.4 1.20.1 on forge.
this has happend on EVERY version of the mod that ive used, and ive looked around and i dont see any fix on it....
what did fix it in the past was too remove the config for some reason which makes no sence.
i just hope that the world me and my family have spent hours on isnt broken.

Did you update from below 1.0.8?
If you have, you'll need to remove the world generation configs for them regenerate and properly function.

no i started with 1.1.4
if i made a second map somewhere else it gave me a new location that did indeed have the cave... but the first map off every cave was faulty, kinda wierd

I think you were just unlucky

that makes no sence. if the map shows me a location to a place that dosnt excist, somethings clearly wrong.

Probably unfixable, minecraft bug, /locate also has this issue, You can regenerate maps by going to the middle of the cave map and waiting for 30 seconds
