Fixed bug where if in the middle of a directional tower upgrade/downgrade and an attack is starts, it would deselect leaving the tower in a 1/2 upgraded state.
Piku Island (The new 7th island) had a few rather interesting traversable routes on the side of some of the steep slopes. These invader walkable areas have been "tightened up". In addition, it was possible to lay a walls with buildings in such a way the "gate blocking" rule didn't trigger, allowing you to block off a path. With these updates it's possible (but unlikely) a save may have used a path that is now not possible, preventing you from placing any walls after the patch. If this is the case, it can be fixed by tearing down walls where its no longer possible to pass, and build new walls.
A few other quite minor fixes.
Patch Notes - b.5.7
New island added: Piku Island - The path from the gate spirals down the tall volcano peak. With colder temperatures and a layout that circles the peak, this island should present a challenge! Unlocked after beating the first 4 islands.
Added new setting to hide environment flowers.
Fixed bug causing the smelters footprint to be rotated 90 degrees preventing it from fitting where it should. This will not effect already placed smelters, but any newly placed ones will use the correct footprint area.
