           ( ( IMixinEntity )( Side.getLocalLevel().getEntity( data.entityId ) ) ).mlib$addGlowTicks( data.ticks );

The server may send an EntityGlow event for an entity the client does not have. this causes the client to crash.

In testing on 1.20.1 this occurred when a client with sufficient latency killed a mob while it was glowing.

This also applies for Invisibility too

Thanks for the report, I fixed it with 4af8cb9 and soon I will release a new version
