1. Dozer remembers last key inputs when you open it's inventory.

Press forward space, then open the Dozer's inventory. It will continue to drive and harvest on it's own.

2. Harvesting a fruit tree with the Dozer never seems to drop fruits.

Wood and seeds drop ok, but no fruits.

3. Harvesting trees at a distance?

Start harvesting any tree, but stop after 2 damage animations.

Drive away 2-3 tiles, even turn around, then start harvesting empty space.

The tree from before should still turn into wood.
