Turret factory producing +80% range mining laser would REDUCE the range when higher amount of relevant components is selected (Lenses I believe).
I suspect the cause of the bug is in the range calculation formula, where the minimum range is multiplied with the turret mod, while the maximum range is not, i.e. :
range = mod*min_range + (max_range - mod*min_range) * scaling * (lenses - min_lenses)
Thus increasing the number of lenses would reduce the resulting range.
Same applies to factories producing turrets with +% damage mod.
Not tested: currently not tested if the produced turret is different from the outcome card that turret factory gives you, or it still retains incorrect stated range.
