Wan2.1 Face Inconsistency

[TWIISTED-STUDIOS]

I'm not sure what exactly has changed or where the change occurred, but over the past week, I've noticed a clear shift in facial rendering. Using the same img2video workflow which I haven't modified there's been a noticeable increase in uncanny valley effects. The faces no longer stay true to the original image; instead, they seem to generate new, inconsistent faces. This was never an issue before, so something appears to have changed in how WAN2.1 handles facial rendering. At this point, I haven't been able to pinpoint the cause. Further investigation is definitely needed to identify the specific changes that have been made.

Or if someone can point me in the right direction as to the fix that would be greatly appreciated.
