Minecraft version: 1.12.2 and above (Paper) Suggested name: PerWorldAdvancements What I want: Our server has a creative plotworld that you can teleport to, and we also have lots of custom advancements to unlock. Unfortunately players can unlock any advancement in any world, including in the creative mode world! At the minimum, a config file where the admin can define worlds that do not unlock any advancements even if the criteria are met would be perfect for my needs. Extra features (such as blocking certain advancements, granular permissions, blocking based on gamemode, etc) are gravy, but definitely not required. Just trying to patch a simple exploit here Ideas for commands and permissions: Other than a reload config command, I don't see any need for any additional commands or perms. When I'd like it by: ASAP, so the fewest number of people possible will accidentally or intentionally unlock advancements in creative.
