Additional context

I can't reproduce it, does the Anchors work correctly until you log out or change dimensions?
Are you playing on a server?
Can you share a list of the mods you're using?

I figured out it was happening because my world name contains a character (':') that windows doesn't like in directories:

[Render thread/ERROR] ESM: Error saving the Anchor listjava.io.FileNotFoundException: ESM\NullPointerException: null\anchors.dat (The filename, directory name, or volume label syntax is incorrect)

so the issue is that it was not saving with world names containing invalid path characters

I don't have invalid chars in my world name and I have a similar issue by which it looks for an anchors file that doesn't exist (because I've never made any anchors):

[16:19:36] [Render thread/ERROR]: ESM: Error loading Anchor list
java.io.FileNotFoundException: ESM\Deez 26\anchors.dat (The system cannot find the path specified)

Shortly after, the server crashes with "Root tag must be a named compound tag" as the reason, but I don't know if this is related.
