Just got a Chaos Pink Bean expedition created, and the Nexon website says you can enter from any channel.. walked up to Forgotten Twilight on channel 18 and it told me I'm not allowed to create a Pink Bean expedition on this channel. Is there a separate map or something? If anyone is able to provide any info I'd appreciate it.
edit: apparently you can change channels in the map before Forgotten Twilight, so we're just searching around for the right NPC text.
edit 2: it's channel 15. I guess if anyone else wants to know, here's your answer. xD
