Sometimes I want to dial down the range on a specific turret to only defend a smaller chunk of land. This lets me carve out more specific spaces to defend, use lakes to my advantage, etc.

I could also use this to set all the ranges on my turrets, upgrade the turret range science, then one-by-one ...

DaveMcW for the win! Switched to all filter inserters into the Rocket Silo and it ran over night with no problems.

DaveMcW's observation is interesting! I can't see what gets loaded because "auto launch with cargo" is on. I assumed it was working normally because the satellite does get consumed and there's only one cargo slot on the rocket. I do have a line with other stuff on it and a fast inserter pointing at ...

update: I deconstructed and reconstructed the rocket silo (to reset the productivity bar) and filled it with efficiency modules. I think it skipped one (what? did I imagine that) but then has had 10 in a row with proper science returns. Derp. Heisenbug gets weirder, but maybe the original theory is ...

OR, is this just something that happens late in the game? I switched to 4 [Efficiency Module 1] and it still skipped. Looks like it's skipping every other launch?

I have my rocket silo loaded up with 4x [Productivity Module 3], I'm launching more than every hour, great. _But_ (seen this twice now) if the last rocket part happens because of a productivity bonus (the yellow bar gets to the end before the green bar) then the rocket launches with the green bar ...
