I had one quest under way, but I was unable to enter the location (level issue I suppose - which is bad, since I shouldn't have been propsoed the quest in the first place - got it in an inn, don't remember what it was).

I had finished a tactical battle, gained a level, then completed a tech and chose exploration.

With the new tech, I hope I can go to the quest location: Give order to sovereign to go there. Left click, and game freezes 5 seconds, then Windows popup appears saying Elemental has ceased to function.

I tried to reload the autosave in order to try and reproduce the problem, but the Load never ends.
