I can find the wine objects in the CS but I can't find the Meshes in the clutter section.
Open the
Clutter folder (don't open any of the folders within the Clutter folder) and look for
winebottle01,
winebottle02 &
winebottle03. If they aren't there, you need to unpack them from the Meshes .bsa archive. You can use http://tesnexus.com/downloads/file.php?id=2097 or http://tesnexus.com/downloads/file.php?id=3311 for this.
And I don't want to completely change their AI package. Just change these certain times.
Then you'll need to modify each individual
Eat package to reflect to time you want them to eat. It would be quicker to make one new AI package, add it to each NPC and remove the old one. Either method poses a problem: AI package overlap. If you want them to eat from 8:00 PM to 9:00PM, and they have packages that run from 6:00PM to 8:30PM, this will cause a conflict. You would have to check the entire AI schedule for each NPC and modify each package as necessary to avoid this.
