Inventory items disappearing.

It's a bug. You can add your "me too" here:

As far as I know, there's no fix yet. I think I saw some people on you tube have some luck and finding them in their household inventory, but that might be a different bug.

Thanks so much for the info!! I will definitely put in my "me too"

This has been happening to me since long before the Eco Lifestyle pack or patch. I couldn't travel anywhere without the newest additions to my inventory getting lost in the process, which was especially annoying when I travelled to the Magic Realm to purchase new wands or ingredients, just for them to be gone when my sim returned home. One workaround I found was to drag those items around in the inventory until they lost the star marking them as new, because the bug only seemed to affect newly collected items.

It's gone from my game now, without me installing any mods to stop it, so I assumed the pre-Eco Lifestyle patch would have fixed it rather than causing it in the first place. But if it's happening to you now, try my method described above. It's not an ideal solution, but maybe it will help for the time being.

Anyone having issues with the presentation board disappearing from your sims inventory after they were done making it good enough to present? Now poof it's gone. They live in student housing so I can't access family inventory even with the enablefreebuild cheat. :(

Yep, I've had it personally once before but I know a lot of others have had this issue. There's a bug report for it over on their official help forums and you should add your "me too" to it. You can find it here:

@Camkat Thank you very much!
