I had a weird experience doing that too. Started as a commando and converted into a gunzerker. The skill tree's reset, but when I started putting points into them they acted weird. Instead of counting up 1/5 2/5 3/5 4/5 5/5 They counted 6/5 7/5 8/5 9/5 10/5. Wasn't that big a deal, but every time I would play hyperion with a friend, the game would freeze as soon as hyperion was killed. I agree with you, there has to be 1 or 2 little things that we are neglecting to do. Happy Gaming :-)
