This generally means your computer is using a font that doesn't have the fancy curly apostrophe being used. Though I would have expected Flash to enforce standard fonts... Speaking of fonts missing apostrophes:
I would agree, except that I have seen apostrophes in other string resources in the same objects (i.e., GM speech), so I don't think that's exactly it.
Highway Robbery #3 Forest Wagon Original Text: They clearly intend to return, for that have left it guarded by a huge Goblin Hulk. Suggestion: that->they
After beating the first battle in Slub'Guts Sanctum, the text under Aftermath has Slub'Gut without an apostrophe.
Which is an odd thing to say right before fighting the Oak Tree King (fourth battle of Black Oaken Heart).
Compass of Xorr - 3 Library "Your path is block by a fierce Mercenary is on guard duty," Seems like it should be "Mercenary who is on guard duty,"
3rd Battle text for the Throne of Strench module, there's a line that says, "Within is the Trog King King, Strench the Pungent, flanked..." I think the text should either be "the Trog King, King Strench..." (comma displaced), or remove the extra King.
Also, in the same place, the GM Text says "Wo, sorry for being such a flake tonight..." Does he mean "Whoa"?
Lord Staffords Treasure module title, should be Lord Stafford's Treasure. On battle 3, the module text reads "Finally, you come face to face with ther infamous Lord Stafford."
The Viscous Tombs, aftermath of battle 2, "The tight confines test your endurance and claustrophobia andi t is with great regret..."
And the aftermath of battle 3: "...and it is a simple matter to climb through it to the surface and beging the march..."
Garnet Demon Portal - Battle 3 module text: "The third room, like the first two rooms, feature asymmetrical patterns in it's construction." No apostrophe should be present in "its" when using the possessive. Also, the immediate following sentence is a fragment: "This time in the form of forboding piles of bones." And the final sentence, "Their hiss and leap to the fray,..."; "Their" should probably be "They".
Garnet Demon Portal Aftermath 4 module text: "An unholy keening sound emanates from behind it, which stops abrubtptly as you heave to rolling ..." "abruptly" is the word you want.
When Against the Cockroaches comes available (after the completion of Garnet Demon Portal), the GM Text from Gary says "I'm getting a bit more confident with this GM-ing stuff <PLAYERNAME>" There needs to be punctuation at the and, right after the player name token.
Against the Cockroaches, Aftermath 1 module text, "...a foul and unnatural addition to the citys ecosystem." Possessive; add apostrophe, "city's".
