Every time I finalize a chracter and I have money left over (i.e. 675,000 left) the program changes it to some strange value (example 675,000 left, get's changed to 68,500 on cred stick). Can this be fixed, and/or explained?

(edited to add: This was supposed to be under the NSRCG -PC thread!)

Could it be that the programm automatically adds those 3d6*100¥ starting cash?

Because 675.000 / 10 = 67.500 ... 68.500 .. That's 1000¥ difference ... and 10 is a rather good average for 3d6 ...

yep. check out SR3 page 63: any nuyen you have left over from character creation is divided by 10, then add 3d6*100.
