It is not good news
Bethseda's new save system is the issue. It uses global data from your saves to prevent Gambling cheating (Saving before and reloading when you fail).
This is Very Bad, If a error or glitch occurs on a save, that screwy stuff can end up messing with your ENTIRE GAME.
Why? Because Beth's system references other saves, even though you are not using them.
I am not a tech guru, so dont yap if I fudged the 'geek speak'
---------- Steps to fix your Archimedes laser
1. Isolate all saves that happened during or at the glitch, Delete Them. There is no way to use the saves after the glitch without keeping the glitch
I have tested this Twenty Times, There Is No Way To Save Your Glitched Save.
