Every so often, when I disconnect from a server, I find that all my severs have been deleted! It's really annoying and unnecessary. Please help!

What I expected to happen was...:
For my servers to all be there when I disconnect to join another one or quit the game.

What actually happened was...:
They are all deleted! Thankfully I have a word document with all of my ips on it but it still takes a long time to add them all again and it's boring.

Steps to Reproduce:
1. This bug happens spontaneously and at random times so it's hard to trigger it
2.It will just happen when you disconnect from a server.
3. Sometimes you lag before being kicked from a server back to the sever screen where all of your servers are gone!
