When looking at the details of Magma or any other block of any kind, statistics for Bladder Efficiency and Sneeziness are shown. This is the smallest of all possible bugs, but inapplicable stats should probably be suppressed in the display.
Alternatively, you could allow magma to pee and sneeze, but that sounds like a feature request.
Steps to Reproduce
1. Click on the stats panel for nearly any non-Dupe thing. 2. It will have inapplicable stats of Bladder Efficiency and Sneeziness shown. Expected: No inapplicable stats.
