Character mistake: The screen showing the cemetery inside Arzenal is full of tombs with utter gibberish names (like Tsliap Stliow, who died in GXVI, apparently, whatever year G is) - Some of this creative engraving does not even fall in the proper physical boundaries of the stone. And it's also labeled "CemetAry."
Character mistake: One of the possible lines of the more heroic soldiers of Gamillas is "Even underestimate a Zaltzian." It should be "Never", not "Even."
Character mistake: Sousuke Sagara's profile says that he does not care for the Arbalest or "it's AI." Should be its, possessive.
Character mistake: Kiryuu Mikage's bio says that her father was "a soldier from the Space CALVARY", instead of cavalry.
Character mistake: Fighting against the Yamato, Schultz might say "Terron monkeys! How did they build a faster than a light speed spacecraft?" One "a" too many.
Character mistake: During Scenario 12 "The Dispeller of Chaos", Sumeragi makes her first appearance in the game botching her very first line as she says "I am IMPRESESED you've actually MAKE yourself a decoy."
Character mistake: A few times during the game (for instance in Haruki's biography) the expression "Coup d'état " is not visualized correctly, with the accented letter replaced by a dot.
Character mistake: One of Jamie's lines against the Para-mails is "Even a beautiful machine can be spoilt when a harlot is at the controls." She says that line even against Tusk's, the one (unambiguosly) male pilot of that kind of vehicle.
Character mistake: One of the possible lines the AI units have facing Getter Robot is "Confirming unit that uses Getter Rays." It's the other way around; 'confirming THAT (the) unit uses Getter Rays'.
Character mistake: Before Scenario 12: The Dispeller of Chaos, the dialogue featuring Ruri has a couple of repetitions who are not part of her character and never appear again in the rest of the game; talking to Misumu, she says "What would that would be", and to the Aesti pilots she says "But first there's someone I want to to [...] first."
Character mistake: One of the most commonly used line from Gamilla's battleship officers is "Terrons are possessed for fearsome battle tactics", when they obviously mean "Terrons possess fearsome battle tactics."
Character mistake: The profile of Yuki Mori from Star Blazers 2199 mistakenly refers to her as "He is 19 years old", probably because the beginning of the profiles of the Yamato are all almost identical and 'copy and paste' was used. The correct pronoun "she" is used for the rest of the bio.
Character mistake: One of the possible messages that happens when Yamato faces Le Chevalier during mission 7 ("Cosmic Crossroads") prompts Kodai to say "This is the ship that is guarding the Pluto base." It's a phrase that fits their previous encounter when Shulz was in fact doing that, but since then the Pluto (or "Plato" base as the Gamillans call it) base was destroyed (by the Yamato itself, even) and they moved past it.
Character mistake: During mission 48, " Lost and Bound", some pilots have a personalized message if they engage ELS units for the first time. Ange's says "if there's a way out of this that DOENS'T involve fighting", with a typo.
Character mistake: Facing Exev in his Imperial (for instance during mission 45), you are very likely to get as one of his messages "Darkness opens it's mouth to consume you", with a bad grammar mistake.
Character mistake: Facing enemies from the Invaders/Getter ray infected faction, Go has as opening line "You don't under the meaning of evolution", missing a rather important part of the word "understand."
Character mistake: In the tactical briefing between mission 41 and 42, the heroes discuss what happened and deal with Yurisha. Sanada refers to previous incident that allowed her to manifest as "our enemy's psychological attack", while obviously it was a "psychic" attack.
Character mistake: One of the quotes by Marida as she attacks aliens is "I can't ignored the threat of invasion!", with an obvious typo on "ignore."
Character mistake: Facing quick enemies (such as the Blamarg), Jill's custom quote is; "You use speed as your weapon? Well, DO SO I."
Character mistake: During her Formation Attack, Ryoko says among other things "The two of us can't lose." But the Formation Attack is done with her, Hikaru and Izumi. It's the three of them.
