PUF 256 famitracker rows results in error

[BThacker]

255 rows works fine, but 256 rows in famitracker (max) causes a compilation error

src\shared.fab:13:7: error: Pattern size does not match track's specified pattern size.
 13 | audio(puf1_music, "../audio/toomanytest.txt")
            ^^^^^^^^^^

It's an easy enough fix to drop the number down to 255, but the error wasn't helpful.

I'm pretty sure I fixed this in v1.8.
