Is there a way you can confirm your bed or nozzle temps? I know for the nozzle that's a really difficult thing to do, it's so small to be able to check with anything.
I ask because with your unexpected crash the other day from your post history, I wonder if your main board has glitched.
A 90c bed shouldn't melt petg I'd think, so something is definitely weird there.
Might be worth trying to reflash your firmware in case the glitch isn't hardware.
What other mods have you done to your printer besides spring spacers?
When you level the bed, is it manually and with a piece of paper to help gauge the distance?
These things have so many places something can go off that it's really difficult to help troubleshoot without being there. Hopefully something in this post helps you out.
Could also be the heat sensor is faulty, damaged wiring, etc. When I compare them, the reported number can be off by quite a bit from the real temperature .
