Mission - Handle errors in Mortar Strike

[Mike-MF]

When merged this pull request will:

• Checks if CBA Setting is actually disabled.
• Checks if any of the target markers are out of range. (It only returns the index, should suffice)
• Checks if Barrages are at least 1.
• All 3 are necessary as this happened in the past day.

Look at those errors out of context, and tell me if you'd know what they are about at all? They need to tell the user "I am this script, this is why I am not working".

Not outside of it, I test the missions now so I'd only need to see this during review really

You do now, maybe you won't in the future.

Does the function still "work" (does not error otherwise) if any of those "errors" remain?

[Mike-MF]

Two are hard failures, CBA Setting & Barrages at 0, can't fire with it. Out of range can still work if you give it multiple targets and at least 1 is within range, but not with the exitWith

Two are hard failures, CBA Setting & Barrages at 0, can't fire with it.

So function should not run in that case at all, to prevent any script errors or missing functionalities.
