FSA comet / mega exo loose, what to look for?

Hi, my drive side fsa comet modular crank is loose. Started when I over tightened the drivetrain on my Kona unit X (single speed).

Now, no matter how much I adjust the crank bolt and retaining cup, it won't hit that sweet spot between too much play and too much resistance.

I am told I need to replace the b/b and the crankset. Seems wasteful to me. I need more information.

What is broken here? What upon close examination should I look for?

Thanks
