Update! I noticed I forgot to implement a functionality: now the AI will create harvesters automatically using the number variables for them, instead of hardcoded numbers... dumb me, the infrastructure for this was all set, but it seems like I never got around to make use of it.
This means that the version number has been bumped up. (Now it's v0.4.1)
(And you believe me when I say that the AI I'm coding with this has took me less than 1 hour to set up and now I'm testing it?)
