Something really weird happened. It seems that magic appended _a to the names of a bunch of my designs and saved it back to file or something?

I am not aware of anywhere in the program code that does this.

I was able to edit the file manually and fix things, but it seems to have made duplicate instances of every included module, but the instances had _a appended to the end. No clue how as I never had any .mag files matching that name. For example:

use bias_distribution  bias_distribution_0
timestamp 1621739502
transform 1 0 -15000 0 1 -22500
box -3000 -4500 3000 4500
use bias_distribution_a  bias_distribution_a_0 ../bias-circuit
timestamp 1622497360
transform 1 0 -15000 0 1 -22500
box -3000 -4500 3000 4500
