Find Session does not always return the correct amount of sessions

Find Session does not always return the correct amount of sessions when finding sessions at the same time.

1. Download the attached project
2. Set PIE to 2 players
3. Within each screen press 'C' to create a session
4. Within each scree press 'F' to Find sessions (Do this for both players before the total is shown)
5. Notice that the player that was used first show 1 session while the second shows 0 sessions
6. Within each scree press 'F' to Find sessions (Do this for both players after the first total is shown)
7. Notice both client and server show 1 session found

Expected: Both versions of the game that are running in pie would return the same amount of available sessions
Result: If done quickly with both players, one will return the correct amount whereas the second will return 0
