Applying Indestructible to a Sediment Strainer (using an Eternal Stella) for use in a Strainer Base still uses the durability and eventually breaks the Sediment Strainer after 300 uses.

If the Sediment Strainer is removed from the Strainer Base at any point before it breaks, then its durability returns to full. This process unfortunately cannot be automated.

The same is true for all the strainers added by the Water Strainer mod.

Is this issue going to be fixed? The Eternal Stella was so expensive to just be wasted...
