Mission 16 part 2 instructions

[Pyrocumulous]

After completing the primary objective of Mission 16, the onscreen message instructs:
"Both primary targets have been destroyed, engage any further targets if you wish.  When ready to depart contact Sentinel using the F10 menu."
This matches up with the mission briefing "Once we have hit the primary target our secondary objective is to attack any SAA targets of opportunity within the FMA or the wider designated free fire area."
Assuming the player does that, they call Sentinel once they are winchester and ready to depart, whom responds "SENTINEL:  Devil 1-2 can you complete secondary tasking?" Being winchester, the player has to decline the tasking and loses the 10 points without credit for following the instructions and destroying additional ground targets.
Not a big deal, just seems odd to wait until the player is done free-lancing additional targets in the free fire area to assign additional taskings.
