Issue
Tried to craft a batch of hydrated tin dust. Put any water container next to tin dust and it will consume the container. I lost 2 thermal expansion portable tanks full of water and one full reinforced ender bucket.

Edit: seems to work fine with vanilla water bucket

Thank you for the report, I will investigate the issue.

The issue is with IC2, I can't fix it I'm afraid. Thanks for the report anyway.
