Okay, solved it – turns out it had nothing to do with the interface at all and came down to a very subtle bug in the sentence segmentation, introduced in v1.10.

> Anyway, this is pretty good news, because the easiest workaround is to just set `--unsegmented` (or pre-segment your text yourself if you want sentence segmentation).

**Edit:** Just released v1.10.1, which should fix the underlying problem 🎉
