The first time I played the Giant Clank boss in the Dreamtime level I took a hit from him which made it so I was unable to get the skill point. I replayed Dreamtime and then at the end, the Giant Clank boss was no longer there and replaced by just a portal ending the level. Does this mean I can no longer get the skill point?? Please help! Is there a way to respawn the boss without starting over???
The same thing happened to me, but I don't actually remember how I resolved it, or if I even did resolve it at all. I'm sure you can fight him again when you start a challenge mode save though, this game's version of New Game Plus.
