In this game, I started noticing my scouts were taking odd paths. I'd tell them to go to a village, and they'd end up somewhere that made no sense. I thought maybe it was just dumb luck with natives getting in the way, but then I found this pioneer out wandering around. If you play out the turn, you'll find him at 29,49. The last command I gave him was a 'w' (pretty sure about that, I do remember specifically that every time I hit the space bar to skip him it took it as 'enter' and asked if I really wanted to end the turn) when he was in Fort Oranje.
git-c79136.
Looked at the game and the log file, but there is nothing conclusive. The wandering unit is headed for a tile just across the river from Fort Oranje, so the first suspicion is just a misclick.
No sign of this recurring, closing as Out of Date.
