1. "Ancient Tree" now needs 14 days instead of 30.
2. Fix a bug that swapped "Ancient Tree" and "Old Tree".
3. Fix "Tall Tree" (unlock when tree is taller than 500 pixels).
4. "So Many Leaves" requires only 100 leaves but a bug made it need 1000 leaves. If you already got it, well....fix it anyway.
