Bug Description

I have NCR v2.2.2 for mc 1.20.1 installed on forge both client and server-side.
However, when pinging the server in the serverlist, it doesn't show up.
When joining the server with the config option client side enabled to join only if NCR is installed I get kicked with the message saying that it's not installed on the server...

The server logs clearly say otherwise, as NCR loads up without any apparent issues, and it's clearly seen logging it's mixin changes successfully.

For refference, here are the mods i'm running it with.

• BetterF3 [7.0.2] (BetterF3-7.0.2-Forge-1.20.1.jar)
• Cloth Config v10 API [11.1.136] (cloth-config-11.1.136-forge.jar)
• EntityCulling [1.7.0] (entityculling-forge-1.7.0-mc1.20.1.jar)
• Ferrite Core [6.0.1
  ] (ferritecore-6.0.1-forge.jar)
• Memory Leak Fix [1.1.5] (memoryleakfix-forge-1.17+-1.1.5.jar)
• Model Gap Fix [1.15] (modelfix-1.15.jar)
• No Chat Reports [1.20.1-v2.2.2] (NoChatReports-FORGE-1.20.1-v2.2.2.jar)
• OptiFine [1.0.0] (OptiFine_1.20.1_HD_U_I6_MOD.jar)
• The Aether [1.20.1-1.5.0-neoforge
  ] (aether-1.20.1-1.5.0-neoforge.jar)
• Xaero's Minimap [24.5.0] (Xaeros_Minimap_24.5.0_Forge_1.20.jar)
• Xaero's World Map [1.39.0] (XaerosWorldMap_1.39.0_Forge_1.20.jar)

Same mods are installed on the server-side (except for optifine of course)
None of these mods should mess with or modify the chat packets,??
I'm lost as to what's going on.

Steps to Reproduce

Self-explanatory

Other Information

I've tried loading the server with just NCR and aether but the issue is still the same.
