Unsure if deliberate, but the gold requirements aren't consistent between stages 1c, 2c, 3c and Final for T2 fabricator.
For T1 Fabricator, all recipes use 1 Gold for 3 wafers (2 and 6 per 60s respectively).
For T2 Fabricator, in contrast for 1c and 2c the recipes use 1 gold for 6 wafers (3 and 18 per 60s respectively), but for 3c and final it's 2 gold for 6 wafers (6 and 18 respectively).
The latter appears to make more sense as a direct scale up of the initial recipes, so looks like the ratios for 1c and 2c are off.
