I'm eager to publish my first save that involves SLCN (or at least molten SLCN.)  I'm making a ceramic/glass factory.  Before I could start on the machines to process the CLST and SAND, I tested the PCLN(OXYG) near the the first STOR pixel (the one near the DRAY is to turn off the one near the STOR,) by changing it's life to 10 to see if the OXYG system was working properly.  The CRAY(SPRK) near the STOR works fine at first but then deletes too much in front of it.  I'm really look forward to puplishing this save.  Could someone please help?  Here's the save below:

EDIT:  I think I fixed the original problem, but now I've run into a different problem:  I've replaced the PCLN mechanism with an OXYG template diagonally copied by PSCN-powered DRAY.  Sometimes it works fine for a little bit but then the INSL that the main machine is made of starts to burn for some reason.  Sometimes some pixels of OXYG wind up floating freely in the air.  Sometimes the machine just stops. To start the process and see these problems unfold, spark the emergency starup button once.

Nevermind, I called off the project since there were too many problems with the machine.
