You know I think rollbacks can be handled several ways:
1. Not doing em at all.
2. Giving everybody equal chance to resubmit and thus to "cheat" as it were.
3. Only allowing the affected individuals to resubmit (in the case of server issues that cause a stale).
Because of the dishonesty of some players this is what makes it so problematic.
However, with an issue that affects all the players like what you are describing, such as weird things going on, number 2 might be the best way to proceed unless everyone agrees to just deal with it and move on and hope for the best.
