Lol, "You tried increasing 'HarvestersPerRefinery' - now the AI still won't build more miners but it is not satisfied with the ones it does build. "
That's my problem, and I suppose it is the same with yuri's harvesters, so I won't increase them either

Thanks!
And this might be a stupid question, but why doesn't any teamtype in the aimd.ini have recruit=yes ?
