Splurgle trophy BUGGED

Check some of the other planets for the priorite, which unfortunately the map won't specify if it's priorite or something else, just "unobtained treasure" (in my case i farmed quite a few data discs looking for the final priorites). I found a few I was missing on Coruscant, and my final one on Nova. Also pay attention to the droids who hold them. They tend to run and disappear fast, especially if enemies are nearby. I had to rest a few times and return to successfully get them, and often used the time slow force ability so i could catch them in time.
