Today I accidentally stumbled upon a weird glitch I probably caused months ago when prepared the previous patch: all ashtray models were missing from the game (so cigarette butts were flying slightly above desks).
No idea exactly how and when (or... why?!) it happened... but now it's fixed.
Also: fragments (basically the unlockable endings) are now saved in a folder named "Fragments" next to "Save" - instead in the Windows registry. The technical reason behind that is if anyone has some problems with them (the registry keys misteriously got deleted, or something like that), fixing it will be much easier from now on.
Don't worry though, the game will still recognise fragments saved into the registry, so this change shouldn't break previous progresses.
