Some of my logistic bots aren't moving at full speed. They're just slower than others in the same network. I don't have any power issues in my base and have researched worker robot speed up to level 4. Any idea what could cause this?
This is how it's supposed to work - if you look at the recipe for logistic bots, it consumes one bottle of despair and one of joy, and produces two logistic bots of two different types: one that is faster, and one that can carry more items at once. Presumably, the cheerful one and the sad one :)
