Been keeping up with the release of 1.5 + 2.5 for PS4 and it turns out there's a pretty nasty bug where the game sometimes crashes on save.

Though some of the bugs, namely a few of the 60fps related ones have been fixed, there are remaining issues with Reaction Commands that still exist, along with a few odd crashes.

I'd love to purchase the game, but the prospect of potentially having my data corrupted is horrible, on top of the fact that many of these bugs were present in the original PS3 remasters. In the mean time, I'm holding off unfortunately.
