How to update baby skins?

Based on the date and opening the .package, this should actually be functioning because the NK patch came out July 23, this was released August 1st, and the baby has the updated skins (separated from the default clothes and now in a diaper) in the .package. I'm not aware of any other patch breaking them either. If you've already cleared your localthumbcache, made sure there are no conflicts, etc. then you could try remaking them by following this tutorial. Just extract the skins from this .package and make a new one with the files they have listed. I don't think that will solve the problem but worth a try though.

You should download the updated invisible crib here, the one you linked is broken since the NK patch.

You can either create an Overrides folder and place the default skins in there, or open the invisible bassinet .package(s), go to the warehouse, delete only the baby skins that are shown (there's no reason for the mod to have them).

Oh glad you got it solved! I forgot to come back to the other thread, sorry.

Your package has a ton of baby skins in it, including old ones, you need to delete them so they don't override your skin replacements.

You sure you're not deleting something else on accident, or that the default replacement skins you have aren't broken? Deleting just the baby skins shouldn't be causing issues.
