Hello,

While using the plugin I've got reports that it leaves w stack worth 0 in the inventory / dropped once a whole stack of fuel gets putt into the oven.

I think there is something wrong with the function that counts all the fuel in the users invetory.

If you are using a plugin like Quick Smelt or something smiliar it is that plugin controlling the Fuel. And depending on what type of stack sizes you are running that are NOT default also play a factor.
