ArPhEx Render Guard is a compatibility and stability addon for Arthropod Phobia Expansions (ArPhEx). It fixes a long-standing crash caused by a null NBT tag during rendering, preventing unexpected game crashes without changing the mod's original gameplay. Designed for Minecraft Forge 1.20.1, it's especially useful for large modpacks and environments where ArPhEx is used alongside other complex mods, such as Superb Warfare.
