Rikti Invasion timeline **Possible Spoilers**

No spoilers in my question, but wanted the spoilers alert in case anything is brought up in the answers.

I may be approaching senility faster than expected, but I seem to remember a contradiction in time frames on when Rikti invaded Primal Earth. I've seen the In-game Timeline, but I seem to remember reading something about the first Riktis being on our side in the 1960s.

Is there an in-game contradiction on the time frames of the invasion? If there is, is there any official reason why the change? Or was the retcon of an invasion pointing to another group, like the Praetorians?

Appreciate any answers you can give; I've been searching for an answer, but have yet to find anything concrete.

I find your lack of signature disturbing.

Where did you see a reference to Rikti in 1960?

I'm wondering if maybe that's the date the aliens (Battalion but I don't have a reference for the name) found their world and not the date the Rikti came to Earth.

No the contradiction wasn't the Rikti but the Shiven's.
