I'm guessing you modified it so every machine has the same number of module slots?
This mod has an option to target a row based on the number of module slots of machines, and uses a slider to configure that, and the game requires that there is actually more than 1 option for the slider. If all machines have the same number of slots, then it will try to create a slider with the same min/max value, which I believe would cause the crash you posted.
I'll work on adding a check for this case that should fix this crash, but in the meantime you could work around it by making at least one machine have a different number of module slots.
