Ever since my new obsession with P3P, I've been playing it nonstop. I am now on August 2nd 2009, but I have noticed something VERY strange. My S-Links, including the Fool Arcana, have simply refused to advance. I get the animation and confirmation of ranking up, but it doesn't happen. I have passed Fool 5, but it didn't increase. The only working S-Link appears to be that of Bebe... Whom I can't access due to the summer. 
 
What should I do? New Game? Dump more hours in and pray that it works? What could have caused this!? Internet searching has yet to yield any explanations or solutions. 
 
Also, I have also had some difficulty in getting Chihiro and Yuko's S-Links started. While they swing by at lunchtime to ask to meet, they aren't where they should be....And I haven't seen them since. AFAIK, they haven't wandered into Tartarus, because I've rescued everybody.

You're fuuuuuuuuuuuuuuucked. 
 
I know what do. 
1) Take P3P. 
2) Put in trash. 
3) Profit.

Sounds like a dodgy copy you've got there? Digital or physical copy?

You haven't been keeping multiple save files have you? 

I've never heard of anything like this before :\
 
Starting over is probably your best bet.
