So I've been using the GURPS Character Sheet (GCS) app to help my friends make characters for my Cyberpunk game, and I noticed something weird. One of the characters has the "Bionic Arms" body modification (Ultra-Tech p209), which includes the "No Fine Manipulators" disadvantage with the "Mitigator: Monthly treatment of Maintenance" modifier for -70% cost. What we didn't notice was that "No Fine Manipulators" (Basic Set: Characters p145) has a note at the bottom which reduces the cost of upgrading ST and DX by 40%. GCS automatically applied this discount to ST and DX point costs, and now we're unsure if that should be the case.
Is this a small oversight with GCS and the upgrade costs should be the normal 10 for ST, 20 for DX since the effect should be mitigated, or is GCS correct? We're just trying to figure this out because if it is a mistake, my friend's character is overspent by about 40 points.
