Issue Description

Apparently some banner patterns are missing. When I try to apply some of them on the banners, they don't display

Hello, unfortunately this is a bug introduced by another mod. There are a few different causes, but it's usually caused by mods building the texture atlas too early or messing with the game data. I would recommend going through and removing mods related to textures/rendering/shaders/performance until you can find out which one and then report it to them.

I've also created a profile with the versions you listed and can verify that the Rune 1 pattern is definitely not missing.
