Describe the bug
Adding a plugin that uses "ProtocolLib" gives an error when reloading the skript.
For example, there is a plugin called "TabList" and "CustomRiding".
A plugin called "Tablist" worked fine with the skript version 2.4.1.
For reference, the error log below is part of many skript files.

https://www.spigotmc.org/resources/animated-tab-tablist.46229/

To Reproduce
I put and experimented with several plugins that use "ProtocolLib".
As an example, when I put a plug-in called "TabList", an error occurred.

https://www.spigotmc.org/resources/animated-tab-tablist.46229/

Expected behavior
Putting a plugin that uses "ProtocolLib" causes an error when the skript is reloaded.

Maybe Skript addon is unmatched with Skript version

Maybe Skript addon is unmatched with Skript version

Skript 2.6 has introduce some breaking changes to addons wich are not up to date. It's maybe this. You have to use up-to-date addons.

Doesn't seem to be related to ProtocolLib; like the error message says, it's likely an issue with one of the skript addons you're using
