What the fuck is this fuckery? Got my leg/waist trackers detected, but when I try to pair 2nd index controller it says "it looks like your controllers are already connected".

So as a test I disabled 1 of my leg trackers, then it did let me pair the 2nd index controller...but got the same message when trying to pair the leg tracker again. What the fuck? I haven't played VR in months but this setup worked fine on this computer back then.
