 017-lds-num=(Default 5, Min 1, Max 32) When steel-plate is not present in vanilla 'high tech' equipment recipes, the cost is determined by the number of "processing-unit"s. math.ceil(n("processing-unit")/thissetting)
 017-pack-type-rebalancing=(Default enabled) Enable the rebalancing of high-end technologies into production/utility 'categories' (FFF-275). For example, level-3 modules no longer use utility science and will use production science instead as they increase production.
 017-techtree=(Default enabled) Enable the 0.17 techtree. Science packs are now unlocked by dedicated technologies and the rocket-silo no longer requires rocket-speed-5 as a prerequisite (FFF-275 & FFF-245). NOTE: Technologies are dynamically assigned a 'science pack technology' as a prerequisite through script (to work with mods). This may not reflect release tech paths.
-017-rocket-victory=(Default enabled) The victory condition for the game no longer requires a payload (satellite) (FFF-275).
 017-nuclear-reprocessing-discount=(Default 1000, Min 0, Max 1400) This number is subtracted from the current cost of nuclear-fuel-reprocessing technology (1500). FFF-275 hints at a major discount to this technology ("The Nuclear fuel cell reprocessing is also drastically cheaper") but does not specify an amount.
+017-rocket-victory=(Default enabled) The victory condition for the game no longer requires a payload (satellite) (FFF-275).
+017-tank-gun-nerf=(Default enabled) FFF-275 states that the 100% damage bonus the tank machinegun provides will be removed.
 017-green-cost=(Default 50, Min 0, Max INF.) This value is NOT official and is an estimate based on the difficulty of similar technologies. Default based off steel-processing difficulty
 017-chem-cost=(Default 200, Min 0, Max INF.) This value is NOT official and is an estimate based on the difficulty of similar technologies. Default based off advanced-electronics difficulty
 017-purple-cost=(Default 250, Min 0, Max INF.) This value is NOT official and is an estimate based on the difficulty of similar technologies. Default based off advanced-material-processing-2 difficulty.
