Delete map_meta.bin in the save file for the folder. You may have to do this both for the server's save and your character's to get it to work.

Only the sever list was removed. Multiplayer functionality hasn't been touched.

They're in %username%\zomboid\multiplayer on Windows (C:\users\EG\zomboid\multiplayer where EG is your Windows username).
