Good evening,
At the toll house, once you engage in a dialog with Anders and you "end" the dialog, the game doesn't let you save. You get a warning saying you can't save in mid-dialog ...
Even after fighter Anders and his crew, and after going to camp for a rest, you can't save - for same reason. Reloading the previous save, before meeting Anders, will not help you. I had to reload the game with the "previous" save that I couldn't save before and then it saved.
I was not able to reproduce the bug
Ok, I think I figured out how to reproduce this bug - I'm not in front of my computer to confirm this, so if someone can confirm this pattern, let me know.
Hyperthesis:
So first, it has nothing to do with Anders dialog.
It's when you shove someone, like the mage at the toll house - you shove her out of the balcony - a dialog will pop and if you DON'T interact with the dialog, when she hit the ground and die, the dialog will close by itself.
-> I believe it's at that moment that the system/game will prevent you to save, no matter what you do. It's like the "dialog" is still open, but you can't see it.
-> Also, Anders crew won't be hostile right away, up until you are in sight with Anders/crew.
If it's the case, your saves (previous one) will get bugged if you reload old save. you will have to quit the game and re-initiate.
There are other places when you can shove someone, that I believe the same behaviour might happened, ex.: the goblin at the first camp on top of the rock, or perhaps the Minotaur in underdark.
if someone can confirm that, it will be great.
