The game is pretty vanilla, only change from default was to make the richness of patches very high. Server is running on a t2 instance in AWS. Its been running since 03/20/2020, so 3 days at this point.
Game state is yellow science, pre-rocket. I was alone, working on expanding base for more Solar. My friend was creating landfill, but I wasn't sure where in the base, as he moved things around. I added a logisitics request for landfill, min 100, max infinity. I hit enter, which exited. So I reset it to 100, infinity, then when I hit the green checkbox, it went into the desync state.
