I just love it when people tell me that the mod does what it can not do. Really really love that. ;-)
Well, that's a question of what you define as light speed. i only see the numbers.
Fact is, there were 2 values in the code, and according to the code they should never have run at 5 but at 0.45 which is still almost 10x faster than default.
but anyway, now they run with 5.0 if the cheat is activated, otherwise with 0.06 * 4
so if you activate the cheat you can see if it's the lightspeed you saw or if it's FTL ;-)
