I am using the 1.19 version of the server and the ViaRewind plugin which allows to join with the 1.8 version. However, if I come to the server with the 1.8 version, the variables of TRITON do not show up. Only [lang]variable.name[/lang] is shown.
Triton plugin require ProtocolLib (cant work with it), and i think its problem in protocollib.

Versions:
triton -> 3.8.3
protocollib -> latest dev
