For 0.19.4, PhoneCall or Compubrah cannot be the only NPCs Enabled in a game session. You must have at least one other NPC enabled such as Amy, Derek, etc.
For example, this is no bueno:

This would also make the game very sad, but only after Amy went bye-bye:

So to fix this issue, make sure you enable at least one other NPC (one associated with a body/Character model, like Amy, or even...Patrick) before you enable PhoneCall and/or Compubrah, and at no point should you DisableNPC all other NPCs except for PhoneCall/Compubrah. The Player just can't be alone with them. Too spooky.
Enabling any other NPC before PhoneCall/Compubrah, just by simply putting them first in the Game Event order, will ensure your story works.
