Found a mistake: Titanium Extractor description says it outputs coal not titanium.
And a bug: the game will crash if you remove a conveyor, leading off a junction, as the junction is outputting onto the conveyor.
Also, I mentioned that the turrets were firing wildly off target in version 1.5, you said it was a mistaken in the maths. This is definitely fixed as of 2.0 for the old turrets, but the newer turrets seem to be suffering from the same, or a similar bug. This is most obvious with the Flak, sometimes firing 90 degs in the wrong direction. Could you have copied the erroneous code to the newer turrets before applying the fix?
