WOL will get and update this month (before TS2). The refugee camp side quest will continue. Besides humans, you will be able to get elves as refugees too. Both forest elves and moon elves. You will also get the rest of production buildings (farm, bakery, kitchen, tailor shop) and leisure buildings (onsen and tavern). The trade will probably not be available yet, as I want to give it more testing and balancing. I would also like to make the refugee camp more interactive. Your settlers will not stay at their place all the time. They will wander around, speak with each other and have various other "interactions".
The update is planned to be out in around 2 weeks from now. Cheers.
EDIT: I have re-uploaded the game on my webpage, as the WOL was missing a texture file and was throwing an error. This should be fixed now.
