Started a new world after the last update and I have been playing it for a few days with no problem (at least with it saving) until a few moments ago. I had a Donkey which had a lot of stuff in the bag, but he was completely gone at load up.
I have been having to quit the game periodically because the memory consumption starts to rise dramatically and then it starts to lag badly while riding a mount (even walking) I have a Geforce GTX 1060 Graphics Card and 16gb memory.
Something else I noticed. I went to pick some apples and ended up picking the whole tree. It has only happened a couple times. Most trees are fine (even apples).
I'm going to just spawn the stuff I had but I wanted to mention it.
