MC 1.14
fabric-api-0.3.0-pre+build.156.jar

I upgraded from antiqueatlas-5.0.0-alpha.1+fabric-unofficial.jar to antiqueatlas-5.0.0-fabric.jar

I noticed that antiqueatlas-5.0.0-alpha.1+fabric-unofficial.jar failed to map shallow water in some cases.

antiqueatlas-5.0.0-fabric.jar seems to correctly map these shallow water areas. Now, if I open the map book after loading the game, the map is correctly drawn:

Notice the lake to the left of the marker/player position.

If I close the book, face west, and open the book again, the map reverts to the old wrong version:

Closing the book and facing North again does not correct the problem:

Is there a way to delete the map data without losing the markers? I don´t mind exploring the world again, I just want an accurate map with the missing lakes and river parts.

If you can also explain why this happens that would be nice too.

This should be fixed in the 5.0.1 release. Please reopen if the issue still persists
