Hi! I was playing Factorio, with many mods installed, this one, and another which let you control vehicles, even the tiny spiderbots. I was thinking; wouldn't it be better if these early game spiderbots also had another 'upgraded' spiderbot, slightly later in-game, which had a small inventory, and maybe even a mini-gun, so in the early game, you can have small spiders shooting and scouting surfaces (if you have AAI/Spidertron patrols mod) and biters. I'd suggest that, if you want to consider this feature, that you can add a technology which unlocks an 'upgraded' spiderbot with probably a 1-5 slot inventory and 1-2 miniguns, with the research having a prerequisite of the spiderbots, with science packs automation, Logistic, and military being required to research, or maybe just placing down a gun turret. But in my experience, the mod's great, I have Renai Transportation and all that installed, and I haven't experienced any problems yet, but that could just be because I haven't done anything to trigger that error. Great work, the mod's very vanilla-esque.
