I was trying to make a fire outside my tent on the 0.58 experimental branch and the items would dissapear when I put them on the floor (Had No Backpack space)this happened with the wooden sticks, the logs and the fireplace kits themselves (Sticks + Rags). The torch I had been using to find my way through the dark however, did not dissapear when I put it on the ground and either did the packet of rice. The items would sometimes take up to 5 seconds to dissapear but most of the time they would dissapear instantly after I crafted it.
I was north of Novodmitrovsk in the hills, to the side of a concrete road.
Before this I had been running from north of Servograd trying to find my way around in the dark back to my camp which me and my friend had built the day before.
