It appears that Omnitron-X doesn't get credit for "Settle the Scores" when it defeats Omnitron. I knocked Omnitron out with Rocket Punch, and I was even sure to make sure there were no other devices first, but I got no credit. Brent reported the same issue. Both of us were using Steam at the time.
Yep, that is a bug specific to Omnitron. It will be fixed in the next update!
Just curious, both of the last two updates mentioned "various bug fixes". Is this one fixed?
Yup!
