I also experienced the invisible guards if you let them escort you to the town.
Do the Tornado and Earthquake spells work correctly? Tornado seems unpredictable and always injures the character who casts it or his companion next to him. When casting earthquake it doesn't matter where I click, the spell gets cast centered on the caster.
In Evelyn's lab, in the first encounter with the cultists, I charmed one and killed the rest to end the battle. Then I attacked the charmed cultist who was following me. Fight started but even after killing the guy, the game never ended the combat even though no enemies were around. In the end I had to reload the game.
