Did you look at the switches and make sure the leaf orientation is the same as what you replaced.
It might look like it's wired correctly. But if you examine the switch itself. And the leaf blades, and how they are positioned. Is it actually wired correct.

I've had this on replacement switches. Where it looks correct but actually physically wired to the wrong blades. Where it's a normal open switch. Wired from the factory to be normally closed.

Quoted from jonnyqtrek:

Good evening! For the switches? I believe so, but just in case I was wrong I went back to the "before" pictures I took and resoldered the old switches in the same orientation. The issues persisted when 1) the new switches were connected, 2) both switches were removed altogether, and 3) after the old switches were restored...

Time to start checking diodes on all the switches in those rows. That share the same wire colors.

Did you reset the plug going to the ball trough optos?
I had random switch firing on my ST because of that, when I had it.
