There's the map (I only compressed the world into a zip file, if I was supposed to do something else please let me know)
The coordinates are 641 65 46
Could it be that the world got corrupted somehow? because I have experienced a couple of more bugs: one time one of my horses disappeared, and another horse that I had in a lead disappeared, but the lead was still there, and when I tried to collect it, it also disappeared, also I have an automatic pumpkin farm and one time the minecart with hopper disappeared, and finally, one time I was transporting villagers to make an iron farm, and when I passed a villager through a nether portal he didn't came out (luckily I had a lot of villagers to spare, but it would have been really annoying if I didn't). The world has never had an addon, but a long time ago I used a chunk texture pack.
It wasn't caused by zombies, the cabin has a little porch with an fence gate, so zombies can't get through (besides there are lights everywhere, nothing spawns near my cabin). I think that the door disappears every time I sleep in a bed outside the cabin, one time I went out the cabin (with the door still there) and walked a couple of blocks, then I realized it was about to get dark, but I decided to keep going and place a bed to skip the night, when I did that I realized that I forgot an axe with silk touch, and when I got back the door was gone.
That's weird. thanks, I'll try to provide more details that could be related
