I second this. The UI for crafting vs upgrading is horrendous. Several times I spent hours mining crypts, transporting the ore ages across the ocean, chopping trees to make coal for the smelting to iron, only to ♥♥♥♥♥♥♥ craft three steel pickaxes instead of upgrading my current one.

I think its to easy to accidentally switch back to crafting from the upgrade UI. Of course nothing several hours of re-grinding crypts can't fix.

On the upside the hard lessons make one more careful but still, I don't mind learning hard lessons in game not so much from ♥♥♥♥♥♥ UI design.

Looking at things from a positive; I am keen for the new content to be released on the master branch. Getting a bit bored now that my base is pimped and guarded by wolves and the loxe are breeding at my door steps. :)
