Weird table access error

The error only happens when my mod entity is adjacent to another of my mod entity. I do not see what is causing this error. Could anyone help me spot the error please?

It seems you are searching for generator in this global roster, but for many records this does not exist:

Code: Select all

	if entity_name == "reactor-steam-generator-01" then
		for k,entity_table in pairs(global.ROSTER) do
			if entity_id == entity_table.record.steamgenerator.id then
				entity_table[3][1].destroy()
				entity_table[4][1].destroy()
				table.remove(global.ROSTER, k)
				return
			end
		end
	end

This looks for record.steamgenerator

However on line 905, a record is added using turbine generator:

Code: Select all

turbine_generator["record"] = {
  ["turbinegenerator"] = {
    ["id"] = event.created_entity.unit_number,
    ["position"] = {
      ["x"] = event.created_entity.position.x,
      ["y"] = event.created_entity.position.y
    }
  },

Which means for this record, steamgenerator is nil

Indeed, I thought of the same on my drive home today. Well, easy fix then. Thanks Klonan
