I am running Construction Drones, Transport Drones, and Krastorio 2. I believe this crash occurred when I had an Oil Pumpjack placed, then put a blueprint down that had Road tiles. The Road tiles overlapped with the Oil Pumpjack. I'm guessing the crash occurred since you can't build on Road tiles and the Oil Pumpjack was already in place.
The mod Construction Drones (0.4.9) caused a non-recoverable error.
