It would seem that there is a glitch or bug on the pc and ps3 version of FF14, where in the screen will go black every now and then, only resolution I've noticed that will solve it is warp back to homepoint or use the warp and intterupt the warp and your screen comes back. Idk why its doing this, but I am sure other ppl are having the same problem. Anyone having this same problem, let me know? Even when you stand still it happens btw SE! Please try to fix this SE!
