- Add empty string check in skinType 0 else branch - Set textureLocation to fallBackSkin(npc) for invalid textures - Add null safety check before returning textureLocation - Prevents transparent NPCs when invalid paths like "customnpcs:textures/entity/test.png" or "teststring" are used
…ture Previously, skinType==0 branch created a ResourceLocation directly without checking if the resource actually exists. This was inconsistent with adjustLocalTexture(), which probes the ResourceManager and falls back on missing assets. Now we call Minecraft.geMinecraft().getResourceManager().getResource(resLoc) and catch IOException. On failure, we fall back to a valid texture via fallBackSkin(npc), ensuring rendering always uses a valid path and avoiding invalid ResourceLocation assignments. This change aligns behavior across texture loading paths and prevents rendering errors when NPC textures are missing.

Description
Adds proper fallback to default skins (Steve/Alex) when invalid texture ResourceLocations are provided for CustomNPCs, preventing invisible/transparent NPCs from appearing.
Problem
When an invalid texture path like
customnpcs:textures/entity/test.pngor an empty string""is entered in the CustomNPC texture field, the NPC appears with a transparent texture instead of falling back to a default skin. While URL-based skins (skinType 2/3) already had fallback logic, local ResourceLocation textures (skinType 0) were missing validation and fallback handling.The specific issue was in the else branch of skinType 0 handling, where
new ResourceLocation(npc.display.texture)was created without checking ifnpc.display.texturewas empty or invalid.Changes
