ComfyUI: Wan 2.2 Loras don't load/OOM after and update

This Reddit thread from r/StableDiffusion discusses a bug in ComfyUI where LoRAs fail to load or cause out-of-memory (OOM) errors when using the Wan 2.2 video generation model following a ComfyUI update. Users report that workflows run successfully with no LoRAs loaded, but adding even a single LoRA triggers an OOM error during the loading stage. The issue appears tied to compatibility problems where certain Wan 2.2 LoRAs only work correctly with specific wrapper implementations, and bugs may exist in the native ComfyUI workflow.
