Please submit a support ticket with your save games if possible.
I was under the weather for a couple of days and then had to catch up on a few things. I'm sending in a ticket in a bit (with the save file), albeit on game that is HEAVILY modded. 
I'll then disable all my mods and play a unmodded fgame and see if the same thing occurs. Might take a while though to recreate.
EDIT:::::
Bah. The save game I had set up that was demonstrating this problem (giving a PW benefit) is now instead giving nothing at all. Different facet of the same bug. But I like things to be consistent, so I am going to try to recreate this bug on a completely unmodded game with the fresh new version of the patch to try to eliminate as many variables as possible.
If I can't recreate it by tonight/tomorrow, I'll stick with the original save file (which was part of a game created during the beta testing for 1.6).
Same issue here... guess GC3 goes back on the shelf till a patch or 1.7.
Might want to send in a ticket as well. If this is an obscure bug more tickets might help them track this down.
