I got the Hayfever recently or whatever its called. Sneezing apparently sometimes causes you to drop items on the ground. However, if my character does that inside my house or a shop the items instantly despawn. Or is this intended? There is also strange clouds floating about inside the houses while I have the fever.
Items on the floor generally seemed to despawn while I had fever.
Being inside a home or a pig shop while having the fever and items in your inventory, the recurrent sneezing did cause the items to drop.
