I don't know how this happened or why, but once I got to the byss mission (third-to-last of it's tier, skipped Tanaab) on my current game, I was unable to create new save games. When I hit "Save Game" it says "Saving jedi_**" and then "Done" like usual, but the new save doesn't show up, autosaves do, but not mine. The strangest part is, the save files are in the folder, but they don't show up in-game. Though I admit to did save quit often (usually after every dark jedi fight).
