so, as robot (or any character) switching with an empty offhand will in fact switch to the empty offhand. robot then can proceed to consume it. I assume it works with others as well, but don't take my word on that. (inf eat did work when I had defpack on, so that could'be been a problem
also, most weaponless characters error when this mod is installed, but some others like molesarge I believe also do. not confirmed, but may be an issue
also possibly make it so that robot can eat a weapon if he has one in his inventory, as getting a laser pistol, and having a cluster launcher + laser cannon won't let you eat the weapon if you only have one weapon in your hand. You have to take the launcher out, switch to the pistol, and make sure you don't accidentally eat the launcher when it goes to your main hand, from your offhand, and the pistol goes to your offhand
