I just remembered--something like this used to happen just before LW started displaying vendors in the Searches and Downloads. 2.8.*?

Once vendors could be displayed, I noted older LW's (~2.3?) or others new to swarming might overwrite the file and start it from scratch. Posters would ask to turn swarming off to avoid this. Major irritation!

Perhaps an older vendor is involved here too?

I'll just go now and gum my mashed potatoes sonny.
