I mean I've picked up on the general method. You can get the map fragments as a random event, but Ive only earned two this way. I bought a couple from the shops but I'm not sure if theres an intended way, or an easier way to get random events than just marathon-ing through slots/M&M/etc.

I wouldn't be too pressed about unlocking it since Ive only been on the site a weekish but for the last 3 days shinwa has sent me to carl, who is locked behind omen island

If you want, you can let me know which map pieces you still need (if any) and I'll send them over. I have lots of duplicates.

That would be great! im missing 4-6.

Sent them over. Hopefully you will have access for those quests now. :)
