Not much. I was researching what I thought was a bug in ME3, which hit me last night. I see the patch/free DLC that's coming tomorrow will address it, but it has already got me.
I was having incredible difficulty completing missions last night, and I noticed I had no powers/ammo powers. After the mission I found all my upgrades were gone and I had like 600 billion upgrade points. It's hard to defeat indoctrinated Rachni with nothing but a basic gun
Anyway, I may have to go back to an earlier save, because I had some mad powers levled up just the way I wanted.
