Thank you! That keeps happening, even though it's not systematic (right? :). That's why I put a prompt to save before entering, which I hope you did :)
By the way, if you have that saved game, I could try loading it and forcing that crash to understand what actually triggered it. (you could send the saved game to theangelinnvn@gmail.com if it's not too much trouble)
(edit: it's fixed now)
