Shifty Character Glitch

[Brainwatched]

So I’m a little stumped and looking for any strategies that might have worked for anyone else.
 

I’ve got 28/29 Blizon Crystals and on challenge mode ensured it wasn’t the ones from the rail. I have the two missing from the map that sometimes don’t show up (but are needed for story purposes - thus I’ve hit them already). Stuck at 96% of crystals and last thing needed for platinum.

 

Does anyone have any ideas? I’m a bit reluctant to delete saves and just try the whole thing again but I suppose I’ll have to if needs be. I also contacted Insomniac, but yet to hear back.

I was in the same situation yestarday and my last crystal was one optional in the other planet (Cordelion). For people struggeling go there and you should unlock it straight away as the rails ones are not missable being part of the story. All the others are reachable and most likely it is in Cordelion.

I hope this is the case for me.  It’s either glitched or I, ,issuing one on the second planet.  Honestly thought I had got them all on that planet as well.  
 

I like the game but not enough to ply through all that again.

I had to recollect them on a new save file and then it unlocked for me. I’m almost certain it glitched as I triple checked through all locations and hadn’t missed any.

I got the trophy today, and you only need 29 for the trophy to pop which it will on Cordelion when you hit the final Crystal to get back to your ship in the other dimension after freeing the Dopplegangar Juice creature.
