Create a unit group with several biters, and then give them a "compount command" but with no "commands" field (required API field). The unit_group.set_command does not fail or verify the table contents, but a few moments later, the game exits with this stack trace in the factorio-current.log:

6307.687 Error Util.cpp:77: Unexpected error occurred. If you're running the latest version of the game you can help us solve the problem by posting the contents of the log file on the Factorio forums.
Please also include the save file(s), any mods you may be using, and any steps you know of to reproduce the crash.
Code: Select all
local command = {type = defines.command.compound, structure_type = defines.compound_command.return_last, command = {
{type = defines.command.go_to_location, destination = data.ally_base.queen.position},
{type = defines.command.attack_area, destination = data.ally_base.queen.position, radius = 25}
}}
unit_group.set_command(command)
unit_group.start_moving()
This should be easy to fix. Unit_Group.set_command should verify the API call is valid.
