I noticed the price on at least one of my inactive robots is…odd. I hacked a chicken walker, and it is currently valued at $10. Apparently Walmart was having a sale on military robotics prior to the cataclysm lol.
I figure something like a chicken walker would cost what, $750K to $1M? Small ones used for EOD are usually in the $100k-$200k range.
Also, you might consider putting in a PR to have your mod merged with mainline and the national guard camp mods. This seems like a damned worthy addition to the game to me, and adds a feature which honestly should already have been possible.
