1. Ancient trees are placeable like regular saplings, but only work on dirt or grass block.

2. Low priority

3. Redwood

4. Recieved ancient sapling (5/6). Placed it on podzol. Tooltip saying to only place on dirt or grass block appears after placement. Bonemealed the sapling. Produced normal oak tree.

5. Expected: Ancient tree to grow.
6. Outcome: Oak tree grew.

7. Prevent players from placing on incompatiable blocks, similarly to trying to place a block in a claimed area.

8. The ancient sapling I recieved today was a replacement for one I had accidentally placed and broke (reverting it back to an oak sapling). I was given a new sapling today, so it likely isn't an issue of an outdated item. Also, I probably can't get another replacement lol but it doesn't hurt to ask.

9. Coords: Redwood (+10985 X +63 Y +11914 Z)
