I was reading this thread, which is basically the same issue as mine. Why would Warp need to implement DataSerializable? If I print out my WarpData#toContainer, I get:
MemoryDataContainer{map={ContentVersion=1, WARP=Warp [position=null, name=home, world=world, x=205.55, y=64.0, z=230.7, groups=null]}}which seems to be working fine. Granted, I do get this exception:
[17:07:28] [Server thread/ERROR] [FML]: A TileEntity type net.minecraft.tileentity.TileEntitySign has throw an exception trying to write state. It will not persist. Report this to the mod author
