Game crashes when opening new hotbar/journal...

[Sylleptic]

I've been using Nedra 0.9 and Fenix Arcane V 6, and I really like them, but for some reason on both of them, everytime I open a new hotbar or try to open my quest journal, the entire game crashes...this does not happen with the default ui. What's wrong???

Note, they just started doing this, they were fine before.
