Hi, So I been playing 1.9 vanilla. Cause I wanted to get more into the game then plugins and I use spigot as my jar cause spigot just is amazing at everything. But I noticed not everything in the vanilla 1.9.2 jar is the same as spigot 1.9.2 so I wanted to switch jars (My map has been up for about 1 month now) I change it everything is going smooth. Then my nether world is reset like back to how we first found it. But when I switch the spigot 1.9.2 jar back its all back to normal... Can anyone explain or know what's going on please?
