From work machine I've rerendered the files into the folders they were deleted from. 2 folders with 375 images each. I cleaned up storage on the misbehaving laptop and restarted btsync on it. It synced all files more recent than the folders it messed with before but those two it continue f***ng up, deleting about half rerendered files in them. It deletes the files from my other shares and they are NOT moved to .sync. Only about half the files from each folder shows up in archive on both on work stationary and server. (and it's not the other half missing from the folders, it's random files from the sequences, both deleted and still present ones). Hopefully I haven't lost anything else, more critical, than these two render folders.
