Something terrible has happened. The only trophy i need to get the Platinum trophy is the "A Guy Called Quest" trophy. All my quests are completed, but the trophy is not unlocking at all. I have tried completed some quests over again. But it will not unlock that stupid trophy for me.

Is there any solutions you people in the LBF community know how to fix this terrible bug / glitch? 

I might be able to fix it by deactivating the quests and then completing them again using the create in pod glitch, I can invite you when you are online.
Edit: I'm not sure if this will complete the quests for you or if it will only complete them for the host

Hi and welcome to ! Hope you enjoy your stay

Now for your problem.. This does look like a terrible bug to have, which unfortunately I don't know how to fix, sorry! But I think the only way to fix it, is starting the adventure over again. I'm not saying to do that because I'm not sure if that is the only way. Just if nothing else works. :/

Hello and welcome! And i'm sure there must be a solution. It could even roll out in a future patch if you're patient enough.

Thanks for the replies everyone, i'll try and restart story mode to see if that helps! Diego264, feel free to invite me to your pod anytime! My username on PS4 is "DMBIRK5000".
