Boats and animals and Villagers

Hi, not sure if this is where this goes, but I feel like I should point it out. I'm having a really bad issue where boats keep disappearing after dismounting them. In the past hour (posting at 2 pm) I've lost over 10 boats, one with my donkey and highly valuable materials inside, and have been stranded in the middle of the ocean. They just disappear, no trace of them. I've also had all my animals disappear, all villagers everywhere disappear, and Iron golems disappear.
