Emoney, go away. Unless you've had it happen to you already (I apologise if you have) then stay out of it.
Gyu, it's also happened when I used the Opera browser.
Should I try it with a different browser? So far.. I have only used Firefox, but I should try some different ones to see if it does the same thing. Or I could always try it on one account while using Firefox and have another character on at the same time using Opera, and THEN see if BOTH browsers encounter it, and they'd both be in a Konoha linked location. (That's a lot of ands for one sentence.)
I've been in Rice Field and Water country so far today, and it hasn't happened there.
And the font seems like a normal size to me.
