Gamers have voiced their complaints about a bug that's causing The Elder Scrolls V: Skyrim to become unplayable on the PlayStation 3 version of the game.
The bug happens when save files exceed 6MB in file size. It causes the game to lag by increasing amounts, with the eventual result being that the game becomes unplayable. So far only a temporary solution has been found, but it doesn't take long for the same problem to reoccur.
Bethesda has stated that they're working on a patch for all three versions of the game - hopefully this bug is at the top of their list as it's becoming an increasingly large source of frustration.
