So I didn't actually have to do anything new application-wise, I just received an email from someone at the placement office last Friday (and another one today) indicating that they had found a possible alternative placement for me. The first alternative they offered (teaching English in Samoa) didn't really fit my skill set/the program that I am in for Masters International, so I let them know that and they got back to me with another option (Youth in Development, Thailand) this afternoon.
If you haven't heard anything yet, I would reach out to the placement office to get an update. I know they are working to find alternative placements for everyone, but the sense I got is that they struggling to do so, because there are not that many groups departing between now and the end of the year. I don't know what your situation is, but if you are able/willing to wait until early 2016 to leave, the number of potential opportunities will be much larger it seems.
Anyway, barring something strange coming up again, I'm hoping to be heading to Thailand in January, and the program there sounds really awesome! I hope everything works out for you guys as well.
