Hey. Playing with the 1.18.2 mod. The spider banner crashes the game.

The game crashed whilst rendering screen
Error: java.lang.NullPointerException: Cannot invoke "net.minecraft.client.resources.model.Material.m_119194_(net.minecraft.client.renderer.MultiBufferSource, java.util.function.Function)" because "$$13" is null

It crashes whenever loading a chunk containing an Arachne Pit and it crashes when crafting a spider pattern banner on a loom.

Edit: After more investigation, I've noticed custom banners from other mods are also crashing my game. I think it's probably a different mod breaking them all. Please ignore this for now. I'll let you know if I find out the issue is an incompatibility from this mod.

Edit 2: The issue is definitely not just your mod, because the same issue happens with certain other mods' custom banners even if your mod is disabled. However, the issue does not happen with every mod's custom banners. It seems like there is something different about how Twilight Forest codes their custom banners for example that makes them work. "Kobolds!" banners also work. Yours and "Epic Knights: Shields, Armor, and Weapons" custom banners break.

I wonder if Twilight Forest and "Kobolds!" have their banners coded the "right" way, but it still must be some other mod that is breaking your banners even if they're only breaking because of some non-standard code somewhere in your mod. I'll keep trying to find exactly which mod is conflicting with yours.

Unable to reproduce. There is likely another mod causing the problem.

Fixed in 18.2.4
