Evaporated Mercury is sometimes leaving a 0mcg debris placeholder

Acknowledging the questionable player's choice to create mesh tiles using Cinnabar ore on a platform where magma was being emptied.  The dupes decided to leave a hot magma bottle on the mesh tile instead of placing it into the bottle emptier.   This only occurred once during the removal of all magma from the asteroid but once was enough.  The melted mesh tiles were replaced with steel.  Thinking more about why the mesh tile initially melted it could have been heat from the heavi-watt plate below it.  I added a conveyor belt to move hot igneous from a petroleum boiler and later built a conveyor bridge across the heavi- watt plate to prevent the conveyor heat transfer.

Mercury liquid would have fallen onto the very hot diamond window tiles below and instantly been boiled to mercury gas.  The gas would have been destroyed in the space exposed tiles.  What is interesting is that along the diamond tile row there are still a few tiles that have a debris placeholder for solid Mercury - however the quantity is zero.  The placeholder's temperature is also below zero and I have mentioned this occurrence on other reports.  I believe that there should be no residual mercury solid on those tiles.

Most of the mesh tiles remaining above the thermal storage area made from Cinnabar on the save if you want to create more instances.
