Updated to 1.21.3 The items now use custom data component types because of that, the mod is not backward compatible any more. Just use something like JEI, REI, EMI and delete and replace old item with new one and you should be good to go Hopefully, this will be the last update that breaks backward compatibility
Updated to 1.21.1 Added Player Teleported Added Advanced tuner that can teleport entities between dimensions Added some sanity checks for reading data from items
