If you turn on the safeguard option while starforcing it should ALWAYS be enabled for stars that are eligible to be safeguarded until the player explicitly turns it off. It should then ALWAYS be off until the player explicitly turns it back on.
Current functionality is that you turn it on and then after performing ONE starforce enhancement, and the next star is eligible to be safeguarded it may or may not still be checked. If the next star is not eligible for safeguard it's always off until turned back on.
In other words:
The safeguard should be more of a toggle than a per star checkbox. When "on" all stars that can be safeguarded (current stars 12-16) will be. When off safeguard will never be applied. This will significantly reduce the amount of clicks required for starforcing.
