Wonder Woman vs Gargantua - S1-E7
Revealing mistake: While the circus crowd is gathered around the cage with Gargantua, there's a closeup of the gorilla as he roars and we can see the stuntman's human teeth behind the gorilla's teeth. It happens again in Gargantua's closeup while he's climbing up to Steigler's window.
The Feminum Mystique: Part 2 - S1-E6

The Feminum Mystique: Part 2 - S1-E6

Continuity mistake: When Diana comes home and spins into Wonder Woman there's a plant on the table under the mirror, but when she walks out of the kitchen with Drusilla that plant is on the floor. Then, note the only thing atop the hutch is a crystal basket, but when she changes back to Diana Prince two more large items are atop the hutch, now the plant is back on the table, and a tall lamp has suddenly appeared beside the chair.

The New Original Wonder Woman - S1-E1
Revealing mistake: When the elderly woman fires the submachine gun at Wonder Woman, the sparks created by her bracelets are bigger and brighter than usual, and we can see the wires under both of her arms to help create those special effects.

Wonder Woman vs Gargantua - S1-E7
Revealing mistake: After Erica shows Gargantua the window of Steigler's location, when the gorilla climbs up the building we can see the end of the hairy sleeves, and the wrists/hands of the stuntman in the gorilla suit. Then on his way down we can see the end of his hairy pants at his ankle.

Wonder Woman in Hollywood - S1-E14
Factual error: Wonder Woman is flying to Hollywood, and the iconic sign is shown. However, in the early 1940's (when this season is set), the sign read 'Hollywoodland'.
Answer: Yes, on the first episode of season 2, she is shown on the island, when another plane crash lands, she says, "They sound different from WW II". Later in the same episode a woman gathers background information on Wonder Woman. The woman says, "From 1942 to 1945, she helped the Allies win the war."
