OPAC Welcome Suppressor
I don't know my version or loader
Open the Minecraft launcher and look at the profile you play on — it names both, like fabric-loader-1.21.4. The version also shows in the bottom-right corner of the game's main menu.
No loader in the profile name? Then it's plain Minecraft, and these mods won't run — you need Fabric or NeoForge installed first.
OPAC Welcome Suppressor
Do you ever get annoyed or tired of claim welcome messages when entering and leaving OPAC claims, especially on servers with a lot of small claims? This client side mod gets rid of them by suppressing any action bar messages that begin and end with "□".
That's it. Nothing too fancy :)
