Interesting, thank you for the info!I see this happen from time to time with mags -- they partially deflate, but only one section at a time and in a particular pattern (mine have done it in a clockwise pattern where sections deflate from 12-2 then 2-4 then 4-6, etc.). I don't have an explanation other than maybe it's adjusting its zoox population, but as long as it doesn't completely deflate, you should be fine.
