Duping glitch with crops
Pkrince opened this issue ยท 6 comments
Observed Behavior
Duplication of farming items when placed a bed on crops in fully covered [Blocked for sunlight] in a claimed land where you don't have permission.
Expected Behavior
The farming items should not drop and get duped on ground/hopper should able to collect it.
Reproduction steps
Step 1. Make a small room with wool and put hopper connected to a chest ( for collecting duped items ).
Step 2. Place a dirt in the centre of hoppers and make it farmable using hoe and then break a wool to make light enter in the room so that we can grow crop (for example potato)
Step 3. Fill that broken wool again and then put bonemeal on the crop to full grow it.
Step 4. Try to place bed on the crop [ Requirement : You must not have permission/trust in that claimed area to make this work ]
Step 5. When you place bed, then a alert message comes in the chat saying "You don't have player's permission to build here" but the crop gets duplication and the items get collected by the hoppers

Running without GriefPrevention
- I attempted running the server without GriefPrevention installed.
- The problem does not occur when GriefPrevention is removed from the server.
Running with only GriefPrevention
- I attempted running only GriefPrevention on the server.
- The issue still occurs when GriefPrevention is the only plugin running.
Running on a fresh, clean server installation
- I attempted testing for the issue on a new server.
- The issue still occurs on a new server.
Using unmodified client
- I attempted testing for the issue with the vanilla client.
- The issue still occurs when using the vanilla client.
We appreciate you taking the time to fill out a bug report!
- I searched for similar issues before submitting this bug report.
Sounds like either a server bug or another plugin causing issues. If you can reproduce with just GP present, you should probably report this to Paper.
It's a Bukkit bug. GP is doing the correct thing, Bukkit is not cancelling the effects of the placement correctly.
This only takes place inside of a claim that isn't yours, does this not point to GP?

As an intermediary solution, I have a patch plugin for 1.13+ which should support pretty much any protection plugin here: https://gist.github.com/Jikoo/c0126ce4ad9cc0f5ef3862180e413d80
Binary https://github.com/TechFortress/GriefPrevention/files/11066655/BlockBedCropDupe.zip, rename to .jar
This has now been patched in CB https://hub.spigotmc.org/stash/projects/SPIGOT/repos/craftbukkit/commits/19de3550d85d736cdf1ae0838fe7891576985e49
Looks like Paper is deliberating the chunk API changes from a commit a couple days ago, so this may take a while to appear in various downstreams.
