That might have been a grammar mistake, but now the meaning is not quite right, or at least the intented anymore. There never used to be a male ember, but there were concepts for all frames to have a corresponding male/female counterpart. Ember was initially planned as a male frame, using the Phoenix Ember Helmet as default. My english is not good enough to tell if "was to be" is a proper way to express that (and if not how else to say it, thats why im here :D) but im pretty "used to be" does not fit to the intened meaning.
Due to mechanics released in Update 11.3.0 missions will change owners occasionally. Unfortunately this means that these tables will sometimes be out of date
It means that suppose a node X is right now Survival and after sometime it can change to Defence or something else. Like the thing happened this update many nodes were updated and replaced with spy 2.0.

Change owners, not mission type. That's because when update 11.3.0 was released, when an invasion was successful, that node would change to the winning faction, even though it was in a Planet from a different faction, so we could have a Corpus node in a Grineer planet! This was removed a while back...
What you're talking about is a different thing, mission types changing in a node... they don't actually change, and since update 15.10 you can choose between the regular mission, nightmare, invasion or syndicate at the SAME node. As for Spy missions, they didn't replace other mission types, they replaced the old Spy missions at the same nodes, didn't they?
Well, that's why I contacted you for, I think saying that nodes can change ownersis currently an outdated info, and it would be better to move this text to trivia, like the one I quoted above from the Planets wiki... what do you say?
