My friends Can't see Each other!

[linna2007]

Simple as that. I was talking to my friends.. but then I mentioned one to the another one and they told me they didn't see each other in the game.
Example.
1 can see 2 and 3
3 can only see 1
2 can only see 1
Like they never logged on the game!
I don't know if this is a common glitch, or if it's an compatibility bug, but it's really creepy
Help?

This shouldn't happen. Perhaps the people are on each others blocked lists?

^ yes, what ruby said. when you block someone you can not see each other, it sounds like either 2 or 3 has blocked the other.

that makes sense...
I'll have to check it out with them tomorrow.
