Finally upgraded my hammer, but when I try to hit the mint nothing happens. I've hit it 20+ times in a row but it will not budge

Keep hitting it until you find the hitbox. You will have to hit it with Different angle or spot to get the resource.

I've spent days trying to get into that container. Very frustrated with the hitbox. Haven't been able to glitch inside the container either.

crouch while hitting it. worked for me and friends had same problem

Thanks. Tried lots of crouching and other things. Oh well. Will move on...

I managed to get inside the box while crouching eventually, trying to hit the mints through the opening seems difficult if not impossible at the moment.
