They're starting to go dormant now with all the leaves starting to flop over. A. konjac is still looking good but I'm lifting some early. Last year we had a very wet autumn and I lifted after first frost, petioles didn't flop even then. Several of the tuber had rot which I removed and all grew well this year. Those which had no rot/tuber removed definitely grew much larger. The largest leaf had a tuber about the size of a hardball.
