My cross air vanishes when i try and load my savings so i had to start over, please fix this i don't wanna keep having to start over everytime this happens

And I suppose it's not because you are unarmed and it doesn't come back even if you change weapons. Does it happen with every save ? There are no other HUD elements disappearing, only the crosshair ? Does is happen on every map or is it specific to one ?
Also, in graphic options, it is possible to change the crosshair color and make it invisible.
Or you might have hit the letters "H", "U" and "D" at the same time ? it's a "cheat" to hide / show the HUD
