How to remove legacy data?

TonyFoster · May 16, 2017, 3:43pm

I had a server contain some legacy data come from some plugin. Now, I don’t need that plugin anymore so I decide to remove it, but legacy data still remain and cause player can’t login to server.

Player lost connection when login:

Actually, this is my third post for similar question. xD

It looks like there is a corrupted itemstack in the player’s inventory. You might have to resort to something like an NBT editor for corrupted player items, or MCEdit for map objects. I experienced a similar issue recently with corrupted data on signs, and had to manually remove them from the map with MCEdit.

So, some of legacy CUSTOM data create by data API shall not cause this issue? Because of this kind data were spared everywhere already, I think manually remove them with NBT editor is inefficient.
