Ever heard of the "lying character sheet" phenomenon in cRPG's ?
This is where the character sheet says your character is doing 50 damage with his uber sword of behind-kicking, but when you hit an enemy, it actually only tries to reduce the enemy HP by 20.
Well, the SGL bug in C3C works in a similar fashion:
If you activate the SGA, the F1 screen and the F6 screen claim that you will complete...
(1) ...researching "steam power" in 6 turns, instead of 8!
(2) the next turn it is 5 turns, until completion.
(3) then the turn after that it is 5 turns again! (huh?)
(4) then the turn after that it is 4 turns,
(5) then 3 turns,
(6) then 3 turns again!
(7) then 2 turns,
(8) then 1 turn.
And now you are at 8 turns in total!
So the human interface (UI) tells you it works, but under the hood, the effect of the SGA is completely ignored.
lets call it the: "lying advisor screen effect."
