Thank you for playing and your feedback! It is annoying to have a wood log block the stone when it otherwise would have fallen in. We will be looking at ways to make resource gathering and processing smoother.
I would like to add that the same goes for bombs. The fact that they also push wood and stone away is a major pain in the ass.
On another note: the game as it is currently is way too much of a slog. You can get upgrades WAY too slow for it to be enjoyable to me. I'd personally increase either resource gain or upgrade cost by at least double the current amount.
