IS there any way to see a list of features I've paid for? It's been quite a while, not sure what I have anymore Also, is there a purchased Feature command list? (ie: /fill lava)
Yes, you can do /myfeatures on the server to see your features for that server. They are server specific, so anything you have for Skyblock will show up when you do /myfeatures on Skyblock for example. Also full command list for all supporter features is here: https://ecocitycraft.com/forum/wiki/supporter-feature-commands/
