I have a very weird thing going on with my multisite network. I'm running 3.1 and I have about 8 sites. At random, posts are being moved to the trash on each site. Completely random! The revision history shows it as my username making the last change on the post even though I didn't touch the post. I've reset my password, changed my username, etc. and still it happens. No one else has been given access to delete posts but my account, so it's very strange. Has anyone else had this happen?
