I'll be collecting bugs and dialog errors I discover in this post.
Dialog Errors
Mayor Cecil: when asked about Jake's murder says "...I've known Esmeralda for years. That business between SHE and the Duke..." => "between HER and the Duke"
Mendius: introducing the Fab Five "...sign our WAVER..." => "sign our WAIVER"
Zixzax: "...the ones Star Stones can tame..." seems like the object and subject are switched. Do we tame Star Stones or do Star Stones tame us?
Bibius: "...doesn't have a horn on HIS head..." regardless of gender.
Bugs
Pressing shift+tab to get the Steam overlay makes you draw or sheathe you weapons as if you had pressed tab only.
Not sure if this is intended or not but I'll add it to be sure: finding a Star Stone with a character in jail teleports that character to the End of Time along with the others.
