Hi !
I'm sorry I did not see your message, I have looked into your account and I have found 3 items: 2 on the same creature
(
https://www.gothicat-world.com/creatures/7921096) and one in your inventory, this last one was added on January 19th at midnight France time.
You should be able to add it to any creature, tell me if you are still having the issue.
@Elowen: Plushies and decorative objects behave exactly in the same way now, plushies prevent your creature from having nightmares but that's it, to customize your creatures plushies and decorative objects are the same.
