all torrents disappearing in 1.52

[rustydude2030]

I had many torrents complete and open to seed on multiple trackers in trans 1.52 all organized in to groups. today i tried to dl something from one of the trackers and the torrents were not starting(everything on the tracker showed ok...peers and such and connectable) so i restarted trans an upon restarting the new torrents started dl'n alright but all my completed seeding torrents were gone. the new ones that i had trouble with at first are there thought. i'm somewhat familiar with torrenting and transmission and im pretty sure i didn't changes any settings and definitely sure i didn't accidentally clear them all. what gives? is this a known bug? will i have to re-add all of them manually? thanks. using transmission 1.52 on 12" powerbook g4 1.5ghz, 1.25gb ram on osx 10.5.6
