I converted an advanced config from v3 to a Path.yml for v4 using the command:
/ar convert advancedconfig

AdvancedConfig.yml example: https://pastebin.com/MBNspy7U
Path.yml result: https://pastebin.com/fbQW3GDf

The result "rank change" doesn't exist and on startup I get these warnings:
[Autorank] (Priority 10) You are using a "rank change" abstractResult in path "circe", but that abstractResult doesn t exist!

The rank change requirement has been deprecated and you should change it to a 'command' result that sets the permission group of a player.

Thank you, I already did it. I suggest you to specify this in the wiki section

Great work. I'll put it up on the wiki! Have fun using Autorank.
