I know how you feel. I refused to accept it.
Two timelines has been enjoyable honestly; I've already found and done a lot I didn't in Universe I. It has reduced my progress by more than half. I'm spending quite a lot of time in Universe II. The only downside is a slight am-I-missing-out feeling becaues I'm no longer storming the world plunging towards Act III but I'm not in a hurry.
And I just realised I can go get Karlach in Universe II anytime. There is quite a bit of fighting between the start and where she is but I can handle that.
Then save the grove.
And a dozen impossible missions at Moonrise in Universe I.
No problem.
