Yes. I was once forced to wait 24 hours for my saved settings and spot in the game to come back. I was very relieved. I also had the most recent issue (this morning) of not being able see my friends, in spite of being able to log in. That's what brought me to this forum, but like with the other issue, I applied a little patience and viola!
I really hope this works for everyone.
Sometimes the program logs you out. Being new to this game, or anything like it, I didn't realize it had booted me out completely, and begrudgingly started playing the new game under "anonymously". One day the system gave me an opportunity to log in. I did, and found my game saved exactly as I had left it. I know this is a pain in the #$@, but i hope you find yours the same way. There's a silver lining.
As a result I play both games simultaneously, which taught me that some of the mistakes I thought I made earlier in the game weren't mistakes after all. Now I play with a different perspective.
