Abandoning a combo dimension shows wrong gain #279
Description
Describe the bug
I'm currently running the Nometal challenge (Nom2 + Metal2). When starting the challenge, my highest zone reached for Nom2 was Z0, and for Metal2 is was Z30. Currently, I'm at Z21. If I abandoned the challenge now, I would expect to gain 2%. However, under Perks it reads "If you abandon the challenge now, you'll add 1% to your total Challenge2 bonus, bringing it to 55%." This is wrong. It should read "you'll add 2% ...". I just abandoned the challenge and the bonus did increase from 54% to 56%.
I had the same issue with the Paralysis challenge, with one highest zone being at Z0 and the other at Z30 or so.
