It's the header:
.Trim Birch-bark. "Cord" [effort:0] [phys:hands,one-armed] [assist:1] *CARPENTRY* /15m/ |-1| (patch:5)
(patch:5) is written wrong, it should be [patch:5]
Worked when I tried it with that change.
(But I don't know if it's really relevant to start magically turning eg. birch-bark stuff into cords. )
