There was a known TM bug back in one of the Summer betas apparently that threw some non completion errors. A bit different than this, but maybe it is a leftover issue of sorts.
I'm tempted to try the 12.1 beta, but I think it's unlikely fixed, and I'll probably just wait unless someone reports a fix there.
