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.

where'd you download version ve500f5f?

I assume they meant e500f5f, which is the most recent PR because Appveyor built it last. Really wish Appveyor had a master branch only view to link people.

Looks like a Paper bug due to the recent banlist changes. https://hub.spigotmc.org/stash/projects/SPIGOT/repos/craftbukkit/commits/648196070e5a1f035c3691870c691c20e44b3439

Imma guess you downloaded from appveyor.

Seems like, in addition to the testing you put in, that this issue occurs due to some plugin improperly creating the player object or something, prolly due to a protocol plugin. Jikoo sniped me lol

yes I download recent versions from this site, isn't it yours?

Appveyor also is used to verify that PRs build. You downloaded a build of a PR that has not been approved, so no, that is not an official build.

The same problem here!

This is a paper bug that has been fixed, if you are having this issue, please update Paper or Purpur
