I'm going to put my game designer hat on for just a minute. Are these tokens and powers that you want or need to give to Jana? Is this stuff she needs to have in order to continue to be a productive and surviving member of the campaign? If yes, then while I'm all for branching opportunity structure, you can't just put them in the world and if she doesn't find them, oh well.
That's like making computer game players hunt all the pixels in the room for the one key that will open the door later. If the player really needs the "Key" to make the game possible and fun, make sure they can find it, either by multiple opportunities, or by making it clear. Challenging, yes. But clear.
If they're just cool extras that would be fun for her, then fine, so she misses some of them.
Pardon the donning of the dreaded hat, but I wasn't clear from your statement what you meant.
