this would can potentially affect BBB T3s: the value of dr3_InSeg was slightly larger with the bug, which meant a slightly larger z selection window based on the track direction due to a larger component accounting for the multiple scattering. Realistically only T3s starting in barrel layer 1 may show something, but it looks like it was not visible even there.
