In "Bots Bots Bots!" 2.0.2 the "Simple Robots" technology only requires red (automation) and green (logistic) science, but the "Logistics Robot 1" and "Construction Robot 1" recipes that this technology unlocks both require "Flying robot frame", which in turn depends on the "Robotics" technology, which requires red, green, and blue (chemical) science -- effectively making the robots from "Simple Robots" actually require red, green, and blue science.

So, if the intention was for "Simple Robots" to only require red and green science, then they shouldn't require something that requires anything more than red and green science.

see bots bots bots forked (it will be updated to be balanced with space age and also fix this issue). https://mods.factorio.com/mod/botsbotsbotsfork?from=search

fix finally uploaded (this took so long)

Thank you. I replaced "Bots Bots Bots!" with "Bots Bots Bots! FORKED" and it no longer has this issue.
