I just logged in and got:
"Reached level 10. You received Healer Iris as a present!"

"Reached level 35. You received Platinum Armor as a present!"

"Reached level 40. You received 5x Sacred Crystal as a present!"

"Reached level 45. You received Platinum Armor as a present!"

Not quite sure where this came from. Did anyone else get these, too? Level 45 seems to be the highest one, since I'm up over 100 now...
