when these missions go from 'special' to 'normal' chains, do you still retain the completion level that you had finished it to from last time?

Lets say i finish it completely, will it just not show up for me when it finally becomes 'normal', or will I be able to 're' do the mission another 15 times..

and the opposite side of the coin is that i finish it 8 times and a bit( or just a flat 8 times), will i have it at the flat 8 completion, or 8 an d a bit?

It will stay exactly the same as you left it, so 8 and a bit, from your example.

thanks for the swift reply I've been sort of wondering about some of the other ones that ive started and havent finished.. wondering if they'll show up and stick out like a sore thumb since ive done atleast one click on nearly every mission in my list.

so if i finish the thing, it will jump over it and go directly to the next mission?

darn~ i was hoping for more of some of the stuff~

xceti chain gonna be ez thou~

Hah, yeah, that's part of why it remembers, so you can't get double the rewards.
