Hi,

Thanks for working on this great-looking mod.

Loading current version 1.0.6, found what looks like forgotten debug message in prototypes/radiation_noise.lua from "log(serpent.block(effects, {maxlevel= 4}))" line.

Which produces output like this on factorio start:

   3.536 Loading mod Longer_Days_and_Nights 0.0.2 (data-updates.lua)
   3.669 Loading mod MushroomCloud 1.0.6 (data-updates.lua)
   3.680 Script @__MushroomCloud__/prototypes/radiation_noise.lua:86: {
  {
    sound = {
      aggregation = {
        count_already_playing = true,
        max_count = 1,
        progress_threshold = 1,
        remove = true
      },
      variations = {
        {}
      }
    },
    type = "play-sound"
  }
}
   3.803 Loading mod Side Inserters 2.3.5 (data-updates.lua)

Thought to report in case it's just an oversight, which it looks like.
Feel free to send this thread to Trash to avoid clogging the Discussion tab with such trivial one-off issues.

Cheers!
