New to the game this is my first playthrough.

I am in early Chapter 2, after i updated the game yesterday. I ventured to the map call "Lone House", everything was fine until I entered the wizard's basement.
- saved the game after entered, when i attempted to load it i got an error saying something about summon pool.
- i cannot exit the area no matter what (i tried killing the trolls that are fighting the wizard or not or even saving the wizard) no changes, everytime i tried to exit the basement i hit a massive lag and nothing happens.
- save/loading in other areas seems to work fine.
- tried loading a game from an hour ago in kingdom headquarter i replayed all the way to the lone house area, same result.

Kinda stuck, please help!
