I’m not sure I understand the point about needing to become a true soul. It sounds to me as though you’ve just exhausted the romance content in EA but I’m sure there’ll be more in the full release, whatever options we pick with respect to the tadpole.
Regarding overwriting conversation triggers, I agree that’s an issue and it’s one that has been mentioned here multiple times. Larian have obviously decided they’re not going to rework this for EA but we’ll have to keep our fingers crossed they’ve been listening and we’ll see this addressed in August when the game comes out properly.
