I’ve had one point in the node Inferno, which requires 25 points, removing the point in Calculated Destruction would have made that point impossible. However, what’s shown is the node below it, Lavamancer. Correct behavior, but wrong text. 
Also, since this is not a ticket system, I hope it’s okay if I add another possible bug: After killing the boss protecting the lance in chapter 7, I died from one of the many ground effects it has. After reviving, I could still collect the loot, but the boss was reset and alive again. From a player perspective, bosses resetting when I die is fair, but resetting after I’ve killed them felt a little harsh. Not sure if that’s intended, a bug, or a technical limitation (because of the zone always resetting as of now). Just thought I’d add it either way.
