Help for Fixing Sims 4 Eyelash CC

Could you be more specific? What do you want to fix? Categories? Texture space?

Example: One version of kijiko's eye lashes are in category glasses and are mapped in glasses texture space. When worn, they will take off glasses.
The second version are in skin details and are mapped in rings texture space. That means they will conflict with rings but can be worn with glasses.

You can change the category in Sims 4 Studio to the new eye lashes category so they are kind of sorted, but the bahavior will be the same.

The space for EA eye lashes is so tiny that it makes no sence to move them into that texture space.
