The message field in u_roll_remainer does not actually work

[Standing-Storm]

Describe the bug

The u_roll_remainder documentation mentions a message field that allows the game to explain what was rolled when a recipe, spell, etc is granted to the player. However, attempting to use this field causes hallucinatory JSON errors (like claiming that u_roll_remainder itself is invalid).

Attach save file

N/A, occurs on load (and requires JSON modification)

Steps to reproduce

1. Place the following JSON somewhere in your data so it loads:

{
    "type": "effect_on_condition",
    "id": "EOC_ROLL_REMAINDER_MESSAGE_DOES_NOT_WORK",
    "effect": [
      {
        "u_roll_remainder": [ "STR_UP" ],
        "type": "mutation",
        "message": "You got a mutation!  Those gainz",
        "true_eocs": [ "EOC_NONE" ],
        "false_eocs": [ "EOC_NONE" ]
      }
    ]
  }

2. Attempt to load the game.
3. Hallucinatory JSON errors

Expected behavior

The message field functions as described in the u_roll_remainder documentation.
