Plugins messing with server internals will need to update, idk if there is a concession to provide a level of compatibility for this stuff

[MillionthOdin16]

This is a pretty significant issue. Many plugins have issues and I can't update because of this

[Owen1212055]

Well it’s their responsibility to update. This is because they are using unsupported parts of the server.

[Owen1212055]

Closing as this is generally an issue with plugins using NMS, and paper is not responsible for upkeep the use of NMS. It is recommended that you stick to api calls inorder to prevent breakages between updates, or understand the fact that you will need to update the plugin manually due to these changes.
