I realized that I misrepresented the issue.Weird - never seen this issue
And so is it in my fully updated and modded R14 - tried some facial types with Hatano Miwa and also Chun-Li from cunihinx: the eyelashes keep staying on their place
So it doesn´t seem to be an issue of the new Repack.
But have no clue what could be the reason.
I would try a new "install", maybe a relevent plugin got lost.
It's not the eye open slider which is causing the problem. It's the eye expression presets. For instance, if you try preset #3 with the default girl, the lashes should detach. I thought it was eye movement from any source because I was messing with both settings simultaneously, but yeah the slider alone does not cause this problem.
I can sort of address this with the blend shapes feature in studio so at least there's that. Thanks for checking.
