Hello everyone! I am fairly new to Spigot and this is my first post so please forgive me if I mess something up. The "read firsts" don't really give a lot of info. Until a few days ago there haven't been any problems. Then on our creative flat redstone world I had this same issue a few days ago. It wasn't that big of a deal then. I used world edit to copy/save what was there and remade the world, loaded saved schematics and pasted them. However this same issue has happened on one of our other more delicate/more used worlds yesterday. I spent all day yesterday trying to figure out a way to fix it without having to copy and paste every single thing back into the world that was done within the past 2 days (since my last backup). I am trying to not only fix this but I would also like to figure out what the issue is that is causing this to happen so maybe I can avoid it in the future. Your help is greatly appreciated! http://pastebin.com/2dmQFDW8 Edit: I just tried loading the world up locally and not only did I not have any issues but when I put it back on the server the issues were gone. I would still like to know what is causing this in order to avoid it in the future if anyone has any info.
