Can't break any stone or wood.

Started playing the demo version today and can't break any stone or wood with the pick or ax. I can break torches, I hunted a cow and a rabbit. But I can't break any stone, gravel or wood at all.

I can kind of see cracks starting to form but they disappear as soon as I stop. If I click fast enough I can see the later stages of cracks but nothing breaks and the cracks continuously disappear even if I keep clicking.

Audio works fine and debris from hitting shows up.
