I was not on a mission I did have cargo, limpets and a few Micro cooling hoses. I was going to mining for some Praseodymium. I am working on engineering my weapons.
Were you in a RES? Outside? (just interesting)
I would suggest mining in a medium / high security system with metallic ring ideally, report crimes deinitely toggles 'on'. High Metal may also be OK for Praseodymium (more common ring type, you can also go to metallic/high metal asteroid belts if all you need is a few tons). It's local to me but Salikians, medium security, has metallic ring.
Now whether you're better off inside the RES or outside I'm not sure. in RES .. security ships around but I suspect pirates will come in waves. Outside a RES you're 'most likely' on your own, and may need to bunny hop a little bit, but pirates will arrive a minute or two after you do, and you can assess the situation. Depending on what ship you're in and how well defended, you might blow them up or have to run two or three times (just SC a few Mm away and drop in the same ring). You don't always always see a pirate so you should get lucky (or get to kill an Adder) after a couple of attempts.
If it's all too much (and presumably you need more cooling hoses now?) PM me .. although I'm near Salikians (and you can look up distances in map) I generally have Praseodymium on me (one cannister of hydrogen fuel, per ton Praseodymium sound fair?)

Nah, they are still going for the limpets, too. Not always, but I definitely wouldn't count on them just leaving.
ps. have never once been attacked for my cargo of limpets (zero population, lawless system, no RES).
