Auto-disable restart in cybergrind/sandbox

[carter370]

Is your feature request related to a problem? Please describe.
Lots of times when i enter Cybergrind or sandbox, i forget to turn off the autorestart, and it restarts from a time limit, messing with whatever i was doing.

Describe the solution you'd like
A feature that forces the auto-restart to turn off if you aren't in an actual level
