My old backups (prior to version 4.3.3) took almost 200MB each but now they're 65MB. Because I was worried I examined the file, noticed it was a misnamed ZIP, renamed it, opened it and noticed that only 5 of my 22 custom maps are in there. I don't know how to do a full restore to prove this is the case without risking losing things. I don't know what else, if anything, is missing.
Anything I can do to help??
