Had an interesting bug earlier. I started up the game and went outside to do my morning chores, which includes collecting bait from the worm tub, grabbing loots from the crab pots I have in the smaller pond and putting any trash from those into the recycler... only my recycler had vanished. I doubled checked my inventory to make sure I hadn't accidentally whacked it with something and picked it up, but no. I checked to see if there was a patch that perhaps removed the device (though I'm not sure why) but no, and I could still craft a new one, which I did.
Then I went to the Steam Forums to find out that I was not alone.
Apparently loads of people are seeing things just disappear from their farm, including chests that are full of items! I was thankful at that point that all I lost was a recycler that's easy to replace. There was some speculation that these items suffer durability damage over time like fences do, but that does not appear to be the case either (or if it is, it's unintentional).
The dev posted in that thread that things outside can be destroyed by encroaching weeds and such, but I'm sure that's not what happened to me, since there was no debris in the space where my recycler was, nor even anywhere nearby, and he did comment that regardless, it shouldn't ever happen to chests.
He's looking into it and hopefully will find a bug, but be aware that there's a possibility that things (important ones!) could just vanish from your farm. :/
