Just got this error, I do have other mods as well and reloading a save doesn't reproduce it, so who knows. Reporting anyway.

The mod Robot Army (2.4.20) caused a non-recoverable error.
Please report this error to the mod author.

Hello,

I have gotten this error a few times today. Not sure if there is something I need to change. I am running other mods alongside this one. Thank you for any info you have on this. I really like the mod by the way.
