Rev 238 and T 121 have been completed and lots of of ISS raw images of Titan have come down. Although seasonal clouds over the northern seas are expected not many have been spotted (as best I can tell from my review of the raw images.
A WAC image http://saturnraw.jpl.nasa.gov/multimedia/r...?imageid=361809 taken on 7/25 (below) shows a brighter area that possibly is a cloud (see? below) over Ligeia. A VIMS image http://photojournal.jpl.nasa.gov/jpeg/PIA17470.jpg from several years ago is overlain (no clouds at the time) to see if the shoreline of Ligeia was bright with evaporate, but it appears not. Is it a cloud? NAC Images taken 1 day later seem not to show it but I really do not see cloud movement as was seen in July 2014. http://photojournal.jpl.nasa.gov/catalog/PIA18420

It really does appear to be a cloud, visible in two separate WAC frames:

And yes, the subsequent NAC views show that the cloud candidate has vanished:
