problem solved, big relieve

Someone at Kongregate solved my long time AS3 problem, which I was struggling with 11 months ago. I encountered the same problem again and I posted it on Kongregate, and one hour later, my headache's gone.

However, when I found out that the problem can solved easily by anyone, even myself, I just didn't notice it for the past 11 months, my reaction was: nothing. I felt nothing, I don't care if I was really that stupid to not see the solution in front of me or what so ever, just want my problem to be solved and get done with it. Wonder if that's a proper behaviour for a game developer? I guess not...
