Update 4.1 | 0.8.5 (b598)
I'm working on reproduction right now, but I happened to save the game shortly before the crash happened. If you load the world and let it run for ~30s, an alert will appear about something running low on copper. It crashed during the pan from clicking on that. The other actions I took between save & alert shouldn't factor in, but that's what I'm testing right now.
