you can no longer double tap tab to auto fill a name with /seen

What version of EssentialsX are you running? This was fixed in a recent update.

I thought i was using the current version. My apologies. Its essentialsx.2.0.1. Could you possibly link me the correct version if i am outdated please? for some reason the link on bukkit says its insecure and it won't let me access it.

Okay, I just checked jenkins and apparently I'm using the correct version.

Another bug added as well - when we use /manuadd to change a player group, it doesnt update until the server restarts.

Closing, updated to the new one on jenkins and it resolved the issue.

Sorry!

/manuadd looks like a GroupManager command. GroupManager is not a part of EssentialsX, and EssX does not support it (if you're using a fork, contact them about the issue).

GroupManager is also no longer supported. There is a new GroupManagerX plugin which could be used with minimal changes. Or other permission based plugins like PermissionsEx (PEX). You can find details for each here for whatever server version you are using.
