I not sure whats causing the slot Stacks to be null, when they should be ItemStack.Emtpy. Must be forgetting something obvious.

Many things...

• Don't extend BlockContainer, simply override Block::hasTileEntity and Block::createTileEntity.
• This check is not needed.
• Why is the Gui ID hardcoded here?
• Don't use IInventory. Use IItemHandler via capabilities.

Those are just the first things I could find.

Okay thx, will have a look to see if anything fixes it.
