You appear to be right.  I found it back to normal last night (V~17.4,
reported to vsnet-obs).  It's still interesting, though, that every
observation except one since the last known outburst was consistent with
it holding steady at V~15.7, and the one exception was very soon after the
star was first reported to have faded to V~15.7 in the first place.  
Apparently the star faded past V~15.7 briefly, then came back up to that
level.  Then a week later, I found it at the same level.  I wish there
had been more than just "fainter than" observations in between!
