Sorry for posting this here, but somehow I'm unable to join your Discord server. Submitting the rules agreement just keeps timing out.

Just wanted to note that according to the wiki, the Lands module does not support offline players. However, this has been merged a long time ago. I guess you just forgot to update the wiki. Just leaving this here, because I was asked about this "issue".

Thank you.

Yeah Discord is borked. Thank you for letting us know. I can update it shortly, otherwise if you want to PR it then you can here: https://github.com/Slimefun/Wiki/tree/master/pages
