Ok, this is strange,
i just log in my home computer and notice my gene's dieter lvl/EXP/Hunger/Intimacy was rest back to earlier this morning when i log off before maintenance. Even through i use different computer to play this afternoon and the dieter had lvl to 123 it is now back to lvl122.
Also i got dc a bit earlier when i log back in. The Hunger lvl had reset back to 76 (same as before maintenance) even through it had drop to 69.
Items/zeny on my gene seems to unaffected.
