If you have the Beacon Interface mod installed this crashes when loading a save file or starting a new game.

I don't actually use the beacon interface, but it's a dependency on another mod I do like to use(the Quality Condenser which lets me make quality products without needing to depend on first visiting Fulgora to get recyclers).

I am going to cross report this BTW since I'm not sure which mod is ultimately responsible for the issue

__beacon-interface__/control.lua:63: {
  allowed_module_categories = {
    ["beacon-interface--module-category"] = true,
    efficiency = true,
    productivity = true,
    quality = true,
    speed = true
  },
  history = {
    changed = {
      "module_everywhere_beacon_config"
    },
    created = "beacon-interface"
  }
}
stack traceback:
[C]: in function'assert'
__beacon-interface__/control.lua:63 in main chunk

And this is the relevant assert from the control.lua

assert(#on_created_entity_filters > 0, serpent.block({
  history = prototypes.get_history("beacon", mod_prefix .. "beacon"),
  allowed_module_categories = prototypes.entity[mod_prefix .. "beacon"].allowed_module_categories,
}))

Thanks for the PR! I'll be updating the mod portal soon.
