What is verbuggen and how do you get that away?

I've already read something about this problem with the PC, but I have this problem with my ps4, that I simply can't get a certain trophy, although I did everything according to instructions to get the trophy. Now someone has told me that the game is probably "bugged" because I can't get the trophy. Can one explain this word to a layman like me, because I'm not a computer expert? Also, how can I fix this problem again!

Bug = error.

You can't do anything. At least not directly. Wait for a patch from the developer (Bugfix = Troubleshooting) and try again.

And what mistake?

No idea. I do not know the game.

This mistake can be anything.

The developer simply made a mistake in developing the game

A programming error.

Detroit become human means the game and the trophy (silver) means "partner" that I want to gain

A bug is a programming error. In this case, this error ensures that the success is not triggered although all the criteria are met (ie, the task you need to do for it).

You yourself can do little or nothing. Maybe wait for a patch that makes the trophy playable again. Otherwise there's no other way.

As I said. Wait for the patch from the developer. We can't help you.

As some have already told you.

A bug is a bug in the game, more specifically… A programming bug.
You have little to no influence on that!

On the PC you can maybe do something, because the community sometimes finds ways and means and some errors are really only related to the user's PC.

The PS4 is a completely identical system for every player, the game is identical! Here you can maximally try to delete the game and reload or reinstall from CD. You do not have more options!

Therefore, it will probably mean that you have to wait for the developers to bring out a patch that fixes this bug. If this is known to them at all.
