GrannyGamer, it doesn't matter where you link from to find the markers--some are in different areas of the City and some in the Neighborhoods.
RJR, you're not the only one who is confused--I can't figure out exactly where you are!
First you said that you got the additional
15 markers, which implies to me that you have collected two sets of 15--is that correct? But then you said you still have five
locations to find--after you have collected both sets of 15 markers, there are only four
I don't think sticking your KI into the calibration machine twice would make any difference. If you have found two sets of 15 markers, after you calibrated the second set you should have a link in your Nexus called "Reezero", and you will be able to open the doors at the back of the Great Zero room. Go through them and down the stairs to the left. You'll see four machines in the room--you have to do these one at a time. Push the button and then stick your KI into the one closest to the window on the left, which will bring up a screen with some letters and numbers. When that comes up, PUSH THE BLUE BUTTON THAT IS ON THE SCREEN
. (This is VERY
important--without pushing the button, it won't work.) Now you should have just one lighted marker on your KI. Go to the Kadish Art Gallery and the marker circle should appear in the air for you to click on.
Once you've collected that marker, go back to Reezero and put your KI back into the left machine that is closest to the window. (You may also have to push the button again, I'm not sure on that point.) That will register that marker as collected--now move on to the machine on your right and follow the same process to get a different marker to find....
