Well, these errors were in the beta and rc1 too. I dont think this 2 errors are the problem.
But its also obvious that hammer made a lot of 'bounces'. (100 exactly)
Like this:
GatherLight: 0...1...2...3...4...5...6...7...8...9...10 (0)
Bounce #1 added RGB(1, 1, 1)
I have no idea what they mean but before it were only 7.
