Okay- I have tested the following under v1.3.9b:

1. Checked points earned from a purchase. No doubling of points.

2. Checked points moving from pending to earned. Points move correctly.

3. Checked points being discounted by Group Pricing- After adding ot_group_pricing:Subtract to Advanced Reward Point Calculation Rules. Points are subtracted correctly and are displayed in the order. However the group_pricing is not being subtracted from the customer under Admin- I am working on this now.

I think that those are the only outstanding issues. Please let me know if I have missed any.
