[RetroDays] Harvested alder trees do not change their sprite

[NetSysFire]

Note: Moved from CleverRaven/Cataclysm-DDA#51642. Still happens and it is more appropriate here.

Describe the bug

If you harvest the bark off e.g a blackjack oak, the tree sprite will change appropriately. The same is not true for the RetroDays tileset when you harvest an alder tree. It displays properly in UltiCa.

Steps To Reproduce

1. Find an alder tree
2. Harvest it
3. Observe there is no change
4. Find a blackjack oak
5. Harvest it
6. Observe there is a change
7. Optionally compare RetroDays with UltiCa for this purpose

Expected behavior

The alder tree should look like it is dead to show it has been harvested, just like e.g the blackjack oak.
