From Feudal Wiki
If you want a Feudal update follow these instructions:
- Is the update practical? Will other Feudal users want this, and will it work for ALL Feudal users? If not, do not request.
- Does the feature already exist? Check the wiki and the Feudal page. If so, do not request.
- Be ready to pay. You have purchased the plugin for as is with updates for Minecraft versions, and bug fixes, but we have to pay a developer to create your update requests. Also, it works like any other place you buy stuff. Money first, product (update) after.
- When ready to send us your update request, contact Forseth11 on SpigotMC, and be sure to check the box allowing Forseth11 to add other members to the chat.
