wagon with a deer spawn in the forge after loading the game, because of this game stops working and hangs and have to recreate the world

hello recently I rediscovered my little backsmith shop and I recently found bugs never seen before in the game the bugs in question are the following =

1) when I save the game and then afterwards I go out and return the objects in the room with the bed in the first shop multiply and this thing is repeated every time I repeat the procedure listed above

2) this is the worst bug that can happen inside the game in other words, every time I go out and back from the game, the weapons placed in the dark wood shelves of the first shop and all the handles placed in the boxes of the work table are bagged without being able to use the same for the weapons, they are also forbidden to use if I try to break them in the furnace (which in parenthesis does not make me do) THIS IS THE MOST DISCOVERED ABSOLUTE VERSION FULL OF BUG 

WITHOUT TALKING ABOUT ALL THE BUGS THAT CONSTITUTE A DROP OF FPS REALLY ABSURD

P.S = THE DROP OF FPS CANNOT BE A MY PROBLEM AS I HAVE A GAMING PC DISCREETLY AT THE CUTTING EDGE

please solve these bugs your game REALLY DESERVES A LOT however these bugs make it really frustrating if not impossible to play
