livepretend: No word exits in last frame

[Stephen Crowley]

I'm trying to use livepretend, it correctly guesess about 20% of the words, but after about 20 seconds into the audio I get hundreds of messsages...

ERROR: "vithist.c", line 564: No word exits from last frame in block 981
INFO: main_live_pretend.c(92): PARTIAL HYP:
INFO: live.c(239): live_nfeatvec: 13

and it stops recognizing most of the words after this... What could cause this?

Here are my args:
