Just had a thought earlier today for the donation store. I was thinking maybe it would be cool if we could pay like 5-7.50 for a pack of various saplings.
Jungle trees have always had a reduced chance to drop (1/40) and other trees have a 1/20 chance to drop a sapling. The new dark oak trees require four saplings to even grow and you can use I believe 4 jungle/spruce saplings to get the variations. That being said it's pretty easy to see how jungles or some of the other forests can disappear quickly. I know logs/planks can be bought at shops, but it's simply not the same as a tree growing naturally in it's proper biome. It's just a thought, what does everyone think?
