TileEntity Map is missing.

Recommended Posts

Hey all!

 

So I have a custom tile here, and it seems to crash when I try to open it with

Caused by: java.lang.RuntimeException: class com.lambda.PlentifulMisc.blocks.tile.TileEnityCrystallizer is missing a mapping! This is a bug!

at

	super.writeToNBT(parentNBTTagCompound); // The super call is required to save and load the tiles location

and

	writeToNBT(nbtTagCompound);

 

Can't really figure out the problem though.

 

here is the tile

* TileInventorySmelting is an advanced sided inventory that works like a vanilla furnace except that it has 5 input and output slots,
* 4 fuel slots and cooks at up to four times the speed.
* The input slots are used sequentially rather than in parallel, i.e. the first slot cooks, then the second, then the third, etc
* The fuel slots are used in parallel.  The more slots burning in parallel, the faster the cook time.
* The code is heavily based on TileEntityFurnace.
