Hello, When two or more users are on the server and one interacts with the CommandNPC to trigger Quicksell the server crashes from CPU load. I am sure Pex is the issue, since I have removed Pex and the issue did not occur.

PEX version?

I'm currently running Pex 1.23.4, but the server was previously running on 1.23.3.

Unfortunately PermissionsEx is currently unmaintained and no further updates are planned. Because of this, all pull requests are being closed. If you are looking for an actively maintained permissions plugin, take a look at LuckPerms. It is compatible with major server platforms and can import data from PEX.
