I put a Squeaky Puft into some Chlorine to make some Bleach Stone and watched it for cycles. It ate tons of Chlorine and never once made any Bleach Stone. There is another bug report for this but it is a year old so it seems either the bug is back or it never got fixed.
Steps to Reproduce
Put a Squeaky Puft in Chlorine and observe.
