At this point I'm not even sure if I want them to mess with the eyes anymore, because I'm afraid that they will mess them up to the point where my lovely Sims become unrecognizable.
I helped myself out with:
1. CC fix for the brown default lashes. I had to apply them on every Sim but now they have the black color again. If anyone is interested, look on curseforge, it's called Eyelash bug fix.
2. I had CAS pictures of all my Sims, because it's a habit of mine to make a picture of everyone looking straight into the camera. So I was able to alter the eyes exactly like they were before. I used the cheat casclockspeed 0 to make them stand still, I zoomed in on the eyes and all I had to do was lift the upper eyelid a little bit up to match the photos I had. As soon as I did that I could play again because they looked just before the eyemess, no more drunken eyes. 🙂 You could do that even if you don't have before-pictures of your Sims, just lift the upper eyelid up a little bit, really just a tad, until the Sims don't look tired anymore.
3. As for the open eyes bug when sleeping or other animations, there is nothing I can do or fix myself, sadly. I try to use a different angle when I take a picture, to make it less visible, but it is just sad. :'(
4. I did not experience yet the weird eyelids bug, where they clip into the skin, even though I tested it with different movements, where the Sim had to look down. Maybe it depends on the eye preset. For example, some of the eye presets still close the eyes, others (like those most of my Sims have) are not able to fully close.
Maybe these infos are helpful to someone. It sure helped me to enjoy my Sims and their Story again. 🙂 But that said, I really hope that if they do consider touching the eyes again they make sure it's right and EXACTLY THE WAY IT WAS BEFORE, not just another failed eyejob!! I can't handle anymore changes in their appearence. ☹️
