Hi all. This skill tree plugin is really great and I was excited to start working with it but I'm hitting some troubles. I saw the demo skill tree tutorial and I thought I followed it correctly but I'm having some issues.

1. Technical issue - how can I change the size of the tree? It's currently way too big to get more than two lanes to fit on the screen. Also, the name text is overlapped with icons.

See image below.

2. I was testing the skill tree with some events in game. I made an event that changes the character class to the appropriate class with a skill tree. The skill tree shows up with the first skill highlighted.

I then perform another event that gives my character the amount of items needed to activate the next skill on the tree. However, clicking either skill, first or second, doesn't do anything. 

Can someone help me with this? What am I missing? I really want to make use of this if possible.
