Some machines consume buckets when extracting fluids from them. This occurs with cells as well, but this is expected due to their disposable nature. I would assume, however, that buckets would retain their normally reusable nature in the context of these machines. I have confirmed this issue with the following machines, but it may exist in other ones too.

• Geothermal Generator
• Solar Turbine
• Fuel Boiler

thanks.

Fixed. Will be in the next patch.
