Thanks so much that worked!
As for the reason my skill tree is so huge, well that's because in my game each actor has three skill trees and a possible 4th skill tree they may quest for. I am only working on three per actor at the moment though. I believe I only need 5 more skill trees. It's a huge undertaking but it will be worth it.
I also have a question about switches and hidden nodes. Unless I am mistaken I can clearly see that the 2nd to last node in this skill tree is shaded differently. Is it suppose to be that way, if so can I make it look like the others instead? The node does work and reveals the last node (the hidden one) when activated. Also the last node has overlapping text. Would you happen to know why?
Also please don't worry about time. This is just a hobby I enjoy, and I am creating my game alone. No deadlines or anything crazy. I am just happy you find the time to answer my questions.
