I set up the lumberjack hut. She chopped one tree. No saplings fell. There's supposed to be a cap for how long she waits for a sapling before just going on to the next tree, but she waited for over an hour in my game. I was busy with the miner and didn't notice she'd been just standing there the whole time.

I was told to throw a sapling at her to get her moving again. That worked. But the time cap needs to be fixed.
