[Bug] Worker stuck while building

Title: Worker stuck while building

Summary: A starry-eyed, hard-working worker kept building away while the rest of my town went to sleep under the night sky. Unfortunately, this stressed him out such that he started glitching in place where he was (presumably) meant to place some planks. Not sure why this happened here and now, exactly. Similar to this bug, but this guy did not seem to be hungry. Perhaps tired? Do you see them get sleepy or do you just see the Zz when they actually are sleeping?
