Very cool, unfortunately, technically flawed

It's really unbelievable what mass of superhero you can unlock in this game. While many are unusable or only differ slightly from other superheroes, which has however not deterred me all to gather.

And so to my problem and the 3 stars: Since I have all Characktere, the game plunges you up times. The PS4 solves the very sovereign, closes the game gives me an error message and I can go on. So do not pull power cord / forced shutdown more. But does not change the fact that the game is no longer to be completed. I'm still missing some things in the main missions as these, however, always take some time and I can not rule out having to start all over again, it is very frustrating. I would like the Game Platinum, as it was a lot of fun, but that will not be good (for now) possible. Should the problem be solved then there's also the deserved 5 stars.
