Others had reported missing threads in other fora but I could only find the SAS one (looking for similar time stamp anomalies at the end of all forum listings). If you search for mixed (star alliance awards I think, but you just need mixed in the search) in the subject line for SAS you will pop up the thread above.

The thread above now contains postings that seem to have come from a planned FT gathering somewhere. When I first opened it up, it was about the mixed star alliance rewards. When I posted to it in the hopes of reviving it, it looks like it just corrupted it further and the mixed star alliance reward info was deleted.
