My dad and I have this world that we've been working on for maybe a year. But over the past week or so, weird stuff has been happening. First, my horse duplicated, then he disappeared, and then his duplication, or whatever, left as well. Then, our snowman duplicated. I "accidentally" killed one, and now there's 3+ snowmen in our home. We've moved the horses, but one duplicated and another one "triplicated". We don't know what is happening in our kingdom, or how to combat this witchery. If it is something to do with the chunks, then we've just been incredibly unlucky. It all started to happen after we used NBT editor to find my horse, but this has to be a coincidence. Please tell me that this has happened to someone else, and that it is fixable. :/
1.8.9 The latest, it's a personal server, run on my dad's computer. We are the only 2 people on there, and my dad is not one for trolls It's just really frustrating because we had grown attached to our pets, and now it's like no one is safe from the evil witchcraft :/
Well it's possible that my dad is running the server in some other 1.8, but I don't think so. We've been looking around on the internet, but all we found were things like horses duplicating due to a chunk error or something. But we also have snowmen duplicating, and who knows if our sheep have been duplicating... We always have a backup in case stupid stuff happens, but we don't have one that goes all the way back to when I think it first started. The only problem with the duplication thing is that we can't get sentimental of our pets, because they could be gone or duped the next day. But man, is it annoying how there just doesn't seem to be a solution.
Ok this is really weird I would suggest that you make a backup of your world so you can load it back in if something breaks.
I never have heard of a duplication bug of mobs in vanilla 1.8.9 though.
There is in fact such a bug that affects any version since 1.8; it only mentions horses but a comment also mentions other things duplicating, such as Ender chests (or other blocks, as if chunks are reverting to an earlier state, which does suggest chunk corruption, which can manifest as chunks not saving or duplicating entities):
Here is a thread about a similar issue (mobs duplicating and disappearing); it has been suggested that there may be chunk corruption, including a case where they saw a "world hole" (a sign of possible chunk corruption, though it can also occur if the client drops a chunk, in which case it goes away after reloading chunks):
For the last, you may want to mention the issue in this thread, you'll also want to upload a copy of the world to Dropbox or Mediafire so they can check it, but it is entirely possible that there is nothing wrong and it is a bug in the game itself that appears under certain conditions:

TheMasterCaver's First World - possibly the most caved-out world in Minecraft history - includes world download.
TheMasterCaver's World - my own version of Minecraft largely based on my views of how the game should have evolved since 1.6.4.
Why do I still play in 1.6.4?
Thank you very much. Hopefully this is something that can be fixed without too much loss.
