Here also a bug with the shiny trinkets...
I'll tell you step by step what happened
1) Vitellary gave me one and told me that they give of weird energy and every trinket appeared on the map.
2) I explored a bit, got some trinkets, quicksaved the game and exit.
3) I started the game again and loaded it, but accidentally loaded a teleport save (by the way, you should add the option 'load newest save file')
4) I exit the teleport save file and loaded my quicksave, discovering that the shiny trinkets disappeared from the map...
5) After finishing some levels, Victoria gave me a shiny trinket and told me the same thing Vitellary already told me, and the trinkets appeared on the map again.
6) After some hard work I got 19 trinkets, but suddenly there were 2 (!) trinkets on the map. I went to one of them, and discovered it was the second trinket in the game (in the first part)
7) I got the trinket (which I already got earlier, at the beginning of the game) and Victoria told me that I had 20 trinkets (I still had only 19 of them)
8
) I got into the 'place where you get when you have every trinket' with only 19 trinkets, and I also have the trophy for finishing the game. Still don't have the real 20th one...
some screens:
http://i47.tinypic.com/33d9iyw.jpg (spoiler, shows the whole map+a trinket location)http://i50.tinypic.com/mmzc74.jpg (shows that I have only 19 trinkets, while victoria tells me I've got them all)http://i47.tinypic.com/eu4gwj.jpg (shows that the stats tell me that I have 20 trinkets)All the screens were taken right after each other, so I didn't do anything special between taking the screens.
I hope you can fix this ^^
