:) Yes it's good to know Hellogames are still addressing very old problems with the game too. 4 Years after launch we still get good additional content updates plus many bug fixes, and the ones seemingly left by the wayside slowly filter their way back in to getting done. That has happened to some of my old bug reports in the last couple of years, they are slowly but surely getting knocked off the to-do list.
I sometimes wonder if its due to the nature of the game being mostly procedural, that Hellogames may have plans ahead of them (well, obviously they have been doing that and quite often surprising us), which may affect the inclusion of quick fixes technically and so they turn into long term fixes instead when the dust has settled down over the most recent update and its patches.
Anyway going off topic. I just cant get over that the one update which included what I previously thought of as quite a shocking development for us long term supporters .. I didn't actually test in case it had finally included offline players being able to get a Void Egg. Pretty much every previous update I did. I think I was disheartened by the change to the games web page which was changed to include the following ..
"The game features online components introduced in updates (SYNTHESIS, BYTEBEAT, LIVING SHIP, EXO MECH, CROSSPLAY, DESOLATION and ORIGINS) that require Internet connection."
.. I took that as the toll of the bell for those of us waiting for content such as the Void Egg missions now being declared as
needing an online connection. So I kind of gave up hope we would get a new default set of available items in the QS Shop.
So happy to be proved wrong :D

Anyway back on topic, though it was an interesting sidetrack and was relevant enough to be helpful for the OP I think.
I am generally wary of save editors and mods being out of date coming from the background of modding / supporting Bethesda games and the many complications little details like this can inadvertantly throw into a game. But burned in unfixable issues that occured in Bethesda games are a bit of a special case, and honestly I think once you have loaded up an edited save for No Man's Sky, the game will only then save what is relevant back to a new save game, and the next reload of the game would settle down and be fine.
I think the worst it can do is not recognise something you have achieved / completed / acquired in a newer version of NMS (currently maybe the new currency introduced in the Halloween update "Tainted metal" for those scrap merchants on space stations comes to mind), and it simply will not be in your next reload.
I need to get to the stage where "Tainted metal" becomes something I want to preserve and find out if its in the same area of the save as the other currencies .. Long way off just now :)
Edit : Ha!, speaking of Tainted metal ..
