Known Issues

• Bukkit API makes stopping item drops from specific slots difficult to detect. My current workaround compares the dropped item type to the item type(s) in the locked slot(s). This means that dropping items from an unlocked slot will not work if it is the same type of item that is present in a locked slot. I am still working on finding a better solution.
• Stopping block placement when using specified slots is also not yet supported.
