Message 1 :
I have proposed an option "add nexus points" (just like the trainer of Dragon Age Inquisition have an option "add Inquisition points". PWiz told me that CH would take a look but that they think that it could be an element online or a link online for this values. So i have test to start Origin in offline mode and my game in offline too. And there is no problem. The option is still active and i could spend my Nexus points just like online mode.
I hope that it would help CH to make this useful option. I send you again my save (you are just in front of the console to spend Nexus points and there is 2 points).

I have discovert a new planet with the level 4 of climatic danger and the option Immune to Radiation and Life Support not work on this planet. I suppose that the option work until the level 3 of climatic danger.
So i send to CH a save (You are in the tempest, just in front on the planet, and you have just to land).
