1. Anvil Rename Bug (vanilla renaming broken) Problem Players couldn’t rename items in the anvil. The result item would appear for a second and then disappear.

Cause The anvil listener was clearing the result whenever either input slot was empty:

Vanilla rename uses only the left slot (right slot is empty). The plugin logic treated right == null as invalid and forced event.setResult(null). Fix Allow vanilla anvil operations when the right slot is empty.

Before (buggy logic) ```java if (left == null || right == null) { event.setResult(null); return; }
