What Happened Instead

Additional Details

Here is the PNG on the latest branch for the banner pattern, showing it is invisible: https://github.com/TeamTwilight/twilightforest/blob/1.21.x/src/main/resources/assets/twilightforest/textures/entity/shield/minoshroom.png

This bug annoyed me for a whole 10 minutes as I assumed the bug was in my rendering logic (showing banners on tinkers shields) until I realized it was just that pattern broken and it was also broken on vanilla shields.

This also affects the quest ram banner on shields, but that one is invisible on banners as well.
