Disabling that or Factorio and Conquer: Tiberian Dawn clears the issue, both worked together before the update.

"Checked it out, this is because our hidden target dummy for the new Sonic Emitters is an invisible fish entity.
But it seems like Aquafarm Extended crashes whenever there is a fish that isn't mineable. They have a block of code that is supposed to handle it, but it has a bad index so it will never work. Should be a 1 line fix for Honktown."
