Is it the "Invite Friends new!"? The [XXX] under your Viking Avatar? Unless that's actually your Guild tag...
Oooooh, let me guess... It's the "wonderful" lil progress bar on top, graciously telling you that you need to RE-subscribe and RE-like to RE-finish RE-installing the game that you have been playing for quite some time... After all, Level 1217 just don't happen in a day, eh? lol... I get this in at least one fb game every 3-5 weeks. It even happened to me in 9 different games one day last November. If you log out of fb, dump your browser cache and history, reload your browser and log back into fb, Does it still want you to RE-do this? I think its caused by one of those mysterious wandering fb quirks...
Nope, you're wrong. The guy is over 400 Levels above my Viking, but I don't see an "... is a higher level and out of your range message." Pretty misleading, don't you think? If I were a noob I might happily attack him, only to find out that I'm horribly outclassed.
