I have a very peculiar bug that was present in both patch 6 and patch 7. Or, at least, I THINK they might be related.
I think that killing auntie Ethel in her teahouse somehow destroys Gale's need for more magical items.


This is what happened:

In Patch 6 and in Patch 7 I was giving Gale magical artifacts (different ones) and everything worked fine until I killed Ethel in the teahouse.
Gale doesn't react at any of them. I don't even receive comments from my companions that Gale might be interested (for example - staff of crones and everything I find after teahouse).

And on top of that auntie Ethel has a visual bug:

Furthermore, we have a bug that happened before the aforementioned tea house problem:

Gale assimilated Necromancy of Thay two times. At camp, I gave him the book, and he said he will read it and then consumed it. But after I took a long rest, he thanked for the book and consumed it again. This happened before my encounter with auntie Ethel.

Besides, can I report that I'm again attempting to romance Gale and again unlocking his romance scenes is an impossible mission? No? Ok, fine.
