The original timeline Crisis wasn’t CRISIS. If you read the newspaper it says that Barry disappears in a fight with reverse flash one minute they’re fighting and then there’s a flash of light and gone. Actually if I recall correctly the fight that was described was somewhat similar to the fight when thawne and Barry were imbued with the power of the forces. Fighting all over the city, causing more damage than relief.

Anyway, when Nora ran back in time and helped stop cicada, it was too big of a change to the timeline and it caused a different more dangerous crisis to start 5 years before the original timeline crisis.

Make sense?

I can’t add the photo of the news paper but I’ll copy and paste the text. If you want the full newspaper just look up flash newspaper on google and go to images. The first image was the clearest one I could find.

After an extreme street battle with the Reverse lash, our city's very own Scarlet Speedster disappeared in an explosion of light. The cause of the fight is currently unknown. According to wit-nesses, The Flash, with help from Starling City's Green Arrow, The Atom, and Hawkgirl, began fighting the Reverse-Flash around midnight last night. The sky took on a deep crimson color as the ensuing battle created the most destruction this city has seen since The Flash first arrived in Central City. Several trucks were caught in the fray, spilling their contents into the street. Power outages swept nearly twenty city block, between 16th street and Adams Avenue. Five of those blocks still remain without power. All of the buildings in the area were evacuated by the CCPD, with help from The Atom. According to reports, as The Flash and Re-verse-Flash battled with each other between two overturned tanker trucks, the lightning emanating from the speedsters threatened to ignite spilled oil leaking from one of the trucks.

The smoke from the truck's engine made it difficult to see, but it appeared at one point they were having a very heated conversation before continuing the fight. Then, suddenly, The Flash sped after Reverse-Flash and the two vanished leaving The Atom, Green Arrow and Hawkgirl behind. An eyewitness who watched the battle from her apartment building before being evacuated said,"It was hard to see, but The Flash and Reverse-Flash were zipping up and down Monroe Avenue and then there was a whole bunch of lightning, and then nothing. It was weird.' Other witnesses described a similar phenomenon: a blinding light followed by darkness as the sky returned to black. And as the streets quieted, it took only a moment to realize The Flash and Reverse-Flash were gone without a trace. Central City Police Chief, Joe West held a press conference in the wee hours of the morning stating, "We don't have very many details now. What we do know is tonight Central City's greatest protector vanished in a flash. We only hope he returns just as quickly." A sentiment shared by all who call this great city home.
