Hi,
Unfortunately I am not sure how it happened exactly. It happened only once randomly when I used Oken's thuder just after next level started (that only thing I remember about that). I tried if I can reproduce it somehow again, but it seems not easy to reproduce. For me it happened only once for all times I played.
If I will be able to reproduce it again I will update.
While trying to reproduce that last issue I run into another one:
That happened when I tried to move randomly tokens just after I used one of the available powers (I think it was "Ziul's cool breeze").
