I really appreciate the shrimp video, thank you.
I don't know if I can avoid abominations exploding in inconvenient places generally, but they are definitely bugged somehow, as they will explode immediately on spawning sometimes, if their 'Find Remote Location' check fails. I will have another look at it.
At the moment there is such an abundance of coal it hasn't been necessary to make roots indestructible, but it probably will be further down the line.
Clay is renewable via creatures vomiting dirt, but it becomes very slow, and I do plan to add a new source for it. I will also want to add a new sink for clay, so the entire map doesn't fill with roads.
I will be making roads destructible, but it won't be in tomorrow's update, specifically.
Thanks for all the feedback o7
