I think it must've been because I went off and did Legions loyalty mission before entering the Omega 4 relay

I'm still about two thirds of the way through my second playthrough on insanity, the bloomin' platform battle on the collector ship was a right 'ole pain in the arse

You can do Legion's Loyalty mission before Omega 4 & still save Kelly & the crew, but you must do it *before* the crew are kidnapped. You need to activate Legion & talk to him after the Derelict Reaper mission *before* touching the Galaxy Map. You'll then have time to do his mission. If you hit the map before activating Legion & getting his mission available, the crew will get kidnapped & you will not have time to do any more missions if you want to save them all.

I've not done an Insanity run yet (I think it would frustrate me too much!), but I've read that that section is *the worst* one in the whole game on Insanity. If you can get through that, the rest is apparently straight forward enough.
