I've beaten the game with the "normal" ending (defeat undead core and escape). The ending plays as normal until it gets to the island falling from the sky. Only the first frame of the clip flashes and then immediately disappears leaving a blank screen until the impact sound plays, then the ending continues as normal. Not the biggest deal in the world but annoying nonetheless. Had to look up the ending on youtube to even confirm that something was wrong. Any ideas on causes or solutions?
