Troubleshooting

I only see Leather Armor instead of custom armor!

If using Lunar Client, follow this and make sure the "OF" (optifine) is selected. If using a different client or custom setup, "Optifine" is required OR "CIT Resewn" on Fabric. Read more here.

The skill bar, health bar, or hotbar looks messed up!

If using LunarClient, read this. Follow step 3 and 4. If using another client or custom mods, you've adjusted your bossbar or GUI scale somehow. Try turning off anything that sounds like "Custom Bossbar" or "GUI Scaling". On Vanilla, this should work fine so try the recommended modlist.
