I own TSW2 (all dlc) on PS4 I decided to delete the game entirely to try to put on a fresh install to cure what I perceive as corrupt data, my copy suffers from irratic opening graphics and crashes when using the livery editor. The reinstalled game performance was at last as it should be no more opening video glitches went to use the livery editor and behold all was well it didn't crash well not until I left the editor then the blue screen of death reared it's self again and guess what yes glitchy opening video again ...back to square one, just as well the game itself is basically glitch free but these other items are really annoying....
