@alexthill hi there next time please follow this and post your game version, game launcher, and provide your logs at .minecraft/logs named latest.log

@armanis do .say .
Example: .say .help it will show as .help in global chat

that would be the server fault or you played when Mojang doing maintenance to their Authentications server

@karmaoffallwnr hi there you can use 1.16.4 mods in 1.16.5 and vice versa also to add / install mods make sure you have fabric API installed from the addon marketplace, navigate to .minecraft/libraries/me/deftware/EMC-F-V2/latest-version
put your mods there and make sure they are fabric mods

@kannabannanna because lower than one will slow down

@coincardhacky hi there next time follow the Example Post when creating a post, but for now, that's fine please tell us what launcher and what other mod (if you are using forge version)

@lknotok navigate into GUI and find this

@test123 hi there once you set up your cape on the website don't forget to delete your asset folder (located on .minecraft) and wait for 10 mins for the cape change
