Demolition Woman Tree: Can't Upgrade Past Tier 2

For some odd reason I can’t spend points past Tier 2 on the Demolition Woman tree. I can spend it on other parts of the tree. Is this a bug or is there a reason for this?

Nope…each level requires 5 points to advance. Sucks but it is what it is.

I understand that.

I wonder if one of the finds that boosts your tree has broken the system.

I’m having a hard understanding your problem. Have you actually spent 10 points in the demo tree yet, Points from class mods dont count.
