The trading of all furniture items are currently disabled that including putting it inside a stash, a quick fix was applied and changed all furniture items (category) as mission items, this way they didn’t need to rewrite too much code.
Now every furniture item is considered a “quest” item from the point of the game of view, of course, there are no quests available to turn them in, etc, this just means you can’t trade them, etc. until further notice.
I came here looking for the same answers. This is a horrendous way to deal with the situation. I didn’t know this, and crafted several trophies with the intent of selling them later, only to discover I fucking can’t put them anywhere.
Guess I’ll just lug around 10 trophies until amazon actually uses the PTR properly.
