Thnx for getting on it, just wanna mention there are other bugs tho. There's a dc bug for all month event and Alpha/Ryuu Jogress quests, a dc bug for buying Clon C and D, and a dc bug for USING Clon B from Kamemon shop, when you re-log, any Tsukaimon, event coins, and Clon B in inventory are gone, and the clon b is replaced with clon D [silk].
For the quest bugs, the dc's don't occur if on channel 0 in Dats for some reason.
*Edited because I am MADE of typos it seems.
*Re-edited, the post below reminded me of another glitch.
My guild leader managed to buy and hatch a 5/5 Tsukaimon, but then dc'd on the way to western outskirts, since then he has been unable to log on that character. He made a new one, and can log onto that one, but when trying to log onto the one with the Tsukaimon hatched, the game closes. No "Fatal Error", no "Fail to connect server", just shuts down. His in game name is rinsha, and the alt is RinRin, if you can help him get his toon back online.
