Using upgrade kitsGot a upgrade kit but cannot upgrade it! Why?
Please check in your inventory if it's a base level (e.g. a level 1 building) or an upgrade kit. You cannot build a level 1 building with an upgrade kit, and in order to upgrade your building from level 1 upwards, you will need an upgrade kit:
|The Crow's Nest - Level 1||The Crow's Nest Upgrade Kit|
This mechanic applies to all upgradable buildings, such as The Ship, The September Cottage and The Crow's Nest.
