Audio problem: In Seaside Hill as Team Chaotix, when you see Eggman's robots at one point, Espio will say, "Are those Eggman's robots?" but the subtitles say, "Are those Eggman's assassins?"
Other mistake: When entering Final Fortress as Team Sonic, Sonic will say "This must be Eggman's headquarters!" however the subtitles make a typing error and leave out the 'be,' reading "This must Eggman's headquarters!"
