There appears to have been a bug in the logic for ground control--which may have been in place for a very long time. I have updated it to work the way I believe it is supposed to work.

The one update we may need to make for the HELP file is that you can get up to 2 ground control affects: one if your arm is hyper-extended and one if your elbow is hyper-extended. But at that point it should max out.
