I know how you feel. But Act 3 is crazy glitchy right now anyway. Like on my Shadowheart romance save, the romance dialogue options and the cutscenes are so, so bugged. And characters are talking about events that haven’t even happened yet. I think patch 3 broke some stuff. So don’t feel too bad about waiting. I think it’s pretty clear that the game needs a lot more work. You could always play up to the end of Act 2 again.
Also, I absolutely love NomTheBurrito’s meme. Nice work
Edit: And I agree that there seems to be very little content where the player connects with Karlach through her tadpole, in contrast to a character like Shadowheart. That’s, I think, likely attributable to Karlach just being a less developed character who was added in later, and it’s a testament to the need to develop her character further. Having more tadpole interactions is low on my list of changes I’d like to see made with Karlach, but it would be a nice touch.
