Talk:Market Place

The main page states that level 10 is required to send resources to other players villages. This is only true if the other player is on another island. Same island transfer is possible with a level 1 marketplace.

Updated Warehouse level needed to 7. It is impossible to upgrade Cave beyond level 3 with a warehouse of only level 6.

Tehnicaly you only need level 6 warehouse to be able to build the market place. Have you tried researching Ceramics?
