Why can't i get Remnant: Cognizance missions?

[Avian]

I was checking github repo for if there is any remnant missions left, and i find out there is a whole cognizance section with 39 missions.

I looked into it and when check out the missions i had done i realize i messed up with one of the quests so i cant resume the questline anymore.

"Remnant: Chilia Intro Log: failed"
"Remnant: Chilia Intro Log: offered"
"Remnant: Cognizance 1: done"
"Remnant: Cognizance 1: offered"
...
"Remnant: Cognizance 5: done"
"Remnant: Cognizance 5: offered"
"Remnant: Cognizance 6: failed"
"Remnant: Cognizance 6: offered"

i did not remember when and how i did fail this quest but i tried deleting Cognizance 6 lines after backing up my savefile it seemed problem solved.

Alas i got stuck at the next mission that called "Take Plume to Nasqueron". The quest want me to land on the gas giant Nasqueron but when i go to the system that "should" have the Nasqueron, doesn't show any landable planet. Lifeforms on the system actually lands on the planet but I can't even click on it.

Can anyone help me with this?

There was a previous mission to deliver something to that planet.

The mission required you to use a special ship in order to land on that planet...

Landing on Nasqueron requires the gaslining attribute, which is only available on certain Remnant ships

mission "Transport Plume" - you need to pick up Plume and deliver him somewere.

Only possibility to fail this mission is fly somewhere far away and lost 5 days. And removing both line

Yes i forgor , my savefile is like a year old or something and it feels like it was ages ago.
