I got both parts of cave key still its shwing not enough material i am annoyed first head ache to downloaf 4 gb data which took 4hrs now this?
I have the same issue
You just have to mix both parts of the key in your inventory in the story part and it will give you the complete key, Crafting the key does not work, but it can be created from the inventory
It is fixed in 0.101.0
