I had an issue where the game would lag so much that I would have to manually quit the game and when I come back all the powdered gold I collected from the crusher just vanished except for the powdered gold inside a chest and my inventory.

Should be fixed in rewrite. Initial release later today

Thanks for response. I feel like I have to say this incase someone decides to tell me off for being insensitive to the mod author because of their over-sensitivity.
