Making a grinder - basically, it turns ores into dusts (not original, deal with it), but anyway, it smelts fine and whatnot (not changed it from the furnace code) but there is ONE thing I cannot figure out:
The progress bars don't update.
Here's the GuiGrinderBlock.java code:

It's 256x256 and I can't see what my issue is.
If you need any more code, please ask and it'll be provided.
