Hi,
I just updated Construction Drones to 0.5 (not sure if related) and tried to stamp down this blueprint: https://pastebin.com/SgdtPwZw
This blueprint is basically a grid containing rails, power poles, walls etc. and Roads from Transport Drones mod. This is in Krastorio 2.
This does not happen consistently. I noticed it usually happening when around 50 drones are placing down Roads at the same time.
The mod Construction Drones (0.4.11) caused a non-recoverable error.
Please report this error to the mod author.
Error while running event Construction_Drones::on_ai_command_completed (ID 113)
The mod Transport Drones (0.5.0) caused a non-recoverable error.
Please report this error to the mod author.
