I don't know if this is for all servers but when you auction a mob spawner (in factions) it turns into a pig spawner. Please fix this, I wasted 50k on mob spawners and they turned into pig. -PewterKat
It's for all the servers, js. I'm 99% sure it's a glitch with he plugin, but correct me if I'm wrong.
There's a way to fix your spawners if you haven't placed them down. Check the spawners name in your inventory. If it's name changed to "Pig Spawner" this won't work. But if some of spawners are still named "Cow Spawner" (for example) you can fix them if you have at least one placeable working cow spawner. Just keep the working cow spawner in your inventory and auction the messed up ones. Then cancel the auction immediately. All the cow spawners should be stacked and working now. The problem has something to do with NBT tags of the spawners. Working spawners start with 3 tags. When you auction them, the change to 1 tag, unless you have other spawners of the same type in your inventory when you win or cancel a auction. You can check the NBT tags by pressing F3 and H at the same time, then open your inventory and hover over the spawners. Good Luck!
@Krissie that is what I had told noobcrew in game when he first tried to fix them on skyblock, the nbt tags. After looking I found it is a permission problem with EssentialsEX and I have stated it several time on the forum.
