make Gold Bar in Autoclave

Have completed quests and no more quests available. Nothing left to chop down. Help, am I missing something?

You have to complete missions one at a time, can't skip any.

You may have found already, but just progress with main missions and you will come across a blue crystal similar to the yellow and green.

When unlocking an island, you don't need to add the necessary items to the ship's hold. It most likely is saying you don't have it bc in ship's hold rather then in warehouse. You only need to add items when need to make something on one of the islands -- such as yellow gearhead on island 2 in part 1.

Oh to get more legs, just repeat the process :)

Click on the spider lair, when the spider comes out click on it and once it's gone you get 2 spider legs.

OK. Found the Blue Crab Claws but still looking for spider legs. Any help appreciated.
