Thanks for the report! It turned out that the autoupdater did not extract mutators (and their dependent files) or translations. We'll need to do some thinking about what the ideal behavior should be, but for now, we definitely want it to extract the plusEmoji files. I've updated plus.zip and plus_install.zip, as well as the autoupdater payload, but anyone who installed 6.1 in the last eleven hours may need to download plusEmoji manually. Apologies!
