A little while ago I completed the last quest: the inventory is empty but the objects of the quest are still visible, look at the attached image is easier to understand. Of course, when i pick up something, this glitch disappears.
BTW, in the Simeon carpentry shop, I can not find the new blueprint (the reward of this quest, the big barn and the big coop)
The items not disappearing from your hotbar is a bug due to reworking basically all of the UI. It should be fixed in the next patch. For now if you just place something else in that slot it should overwrite it and be fine.
As for the barn and coop, are you checking under the upgrade section of the building UI? There is a tab on the right. Assuming, you are then I’ll check into it.
