Im having this same problem. Ive worked extensively with swfs in aftereffects and this is a brand new thing. and so far I’ve tried switching the swfs to read only with no luck. Somehow after effects is altering the swfs. For me mostly reverting to old versions of themselves even after I copied the flash timeline into a new flash file and exported using a different name. But yes sometimes it just wipes them. I’m currently working in cs5.5 but i’m going to go back to 5 and hope for the best.
