A weird interpolation error it’s happening on, at first glance I couldn’t spot the problem

Wow, this is very bizarre. Nothing unusual about outlines, and they seem totally fine in the UFOs. Error persists if start point is changed to the bottom of loop. Maybe something happens when converting to quadratic? Will require further investigation.

Error persists in CFF2!

The Condensed Thin Italic UFO was correct, but it was missing from the latest designspace.

Because this is a significant omission, I am going to patch the 0.869 fonts before we jump to 1.0.
