Just wanting to put this out there because the tail wasn't working for me either but setting the priority to just 99999 and redrawing self suddenly made the tail work. Now it just kinda works with no issue. Not sure if this will help anyone but it worked for me. https://i.imgur.com/2qx0bVp.png
I can't seem to make it broken again.

For additional info, Fresh install, no other mods, empty collections, that auto deduplicate setting is still on in the settings.

I genuinely got no idea why it suddenly works
