Crash when too many attackers?

[Peppe]

So I am trying to trigger an attack whenever I launch a rocket.

My test was just to find enemies around the launch area and set them to attack:
rocket.surface.find_enemy_units(rocket.position, 500*score)
I tell each one find the rocket and attack with minor ADD:
set_command({type = defines.command.attack_area, destination = rocket.position, radius = 5*score, distraction = defines.distraction.by_enemy})

My test run finds ~7000 units.

First run crashes after a few minutes.
I cap the units a few times and now at 2000 units it still crashes. I can keep going lower, but wonder if the crash may be something else:

So, having no idea how the game handles biters, just throwing this out there, doesn't the game consider biters as "groups"? Could you try to find every group of biters within range?

As it stands I think you are just telling every biter within range to find its way to the rocket, so that's 7000 pathfinder calls (which IIRC was stated as being resource intensive atm)
