Hello !I've noticed that when you put an amount of materials that is greater than the size of a natural stack, with the help from another mod or just a normal 1003 bugged out stack of ores,  the ammount that will end up in the furnaces will actualy be the double. In 10 minutes I had 1500 ores of HQM, now I love finding bugs and exploit them for a bit of fun, but this completely breaks the game :P.

Anyway, I just posted this to let the devs know. Have a good day!
