Main path trophy glitch

[fbdbh]

Hey, guys!

 

I'm experiencing an odd glitch; maybe somebody can help me?

 

I have completed the "Main path of the Story", got the trophy, but one of the Story paths didn't unlock my trophy. As you can see on my profile, it's the Jackpot City one: https://psnprofiles.com/trophies/1612-LittleBigPlanet/fbdbh

 

The weird thing is, that the in-game pin was unlocked. Replaying the boss level doesn't do anything, replaying more levels doesn't do anything either. All subsequent trophies unlocked fine.

 

Anybody experienced similar glitches? How do you resolve such thing? I may have had a connection issue or turned to sleep-mode mid-level, because another trophy glitched that day (the 7 day one), but I achieved it one week later.

 

The Jackpot City one... doesn't pop, no matter what I do.

 

Is it possible to resolve this by deleting the save game (I'm reluctant to do so, I made good progress), or preferably without deleting the save game?

Try deleting and installing the game again. If that doesn't help back up your save data on a flash drive, delete save file and have a friend invite you so you can play the level without having to unlock it

Thanks, I'll try.

 

It's just that I noticed that deleting the game also tries to delete save files, or can Content Manager handle the backup? (I'm really new to Vita)
