I just posted this in the English section, maybe someone here can translate to German:
Whether or not your map is locked or unlocked is information saved on the server and not in your local files. So, what you can do to "access" this setting is this: open your options and go to UI settings, click "reset all" at the bottom. HOWEVER if you click "apply" or "OK" then, certain settings in your UI will be reset along with it (UI size and such), including the fact that the map will now be permanently unlocked and movable. If you don't want the other settings to be back to default, you can start the same way by clicking "reset all" in UI settings BUT then DON'T click "apply" or "OK" and just keep your options window open while you drag your map to position, and when that's done, close the options window (again, without clicking "apply" or "OK"). Everything's back to how it was, no changes, but you have now successfully moved your map. And to top it off, your map will still be locked lol. Hope this helped, took me some time to figure this out.
