How is Path of Building expected to behave?
Not throw this error every time I attempt to select something like a skill gem, allocate or de-allocate a passive skill tree point.

How does Path of Building behave?
Throws error after inserting skill gems.
How to reproduce the issue
Not 100% sure.
Try selecting Vaal Domination as a main skill gem. That is when the problem started for me.
Roughly speaking, I did the passive skill tree, items, and everything else then started inputting skill gems.
Then it started throwing the error every time I try to select something.
Note, it it does not throw the error when I switch between the various tabs: Notes, Configuration, Tree, Skills, etc.,.
