[Bug] Very specific Rule assistant AI prompt error

I have created a set of rules which add custom prompts onto characters when they meet certain criteria, eg. albino. I was having trouble with only one applying at a time when multiple where valid as they all added to the positive prompt section, to get around this, I added another condition to the rules which checks if the custom prompt already contains the values the rule would apply. When aquiring a new character, these rules attempt to apply, but the new character has custom prompts not allowed which causes the getter to be comparing a null value to a string and error.

I attempted to fix this by having a rule which always activates and adds a " " to the custom prompt, therefore enabling them, but it seems the checks happen before any rules are applied.

Expected Behavior

Either an option to have the custom prompts enabled by default or a way to check for null in the rule assistant

Current Behavior

As soon as a new character is aquired, an error appears. When the error is dismissed, the game screen (where the details of the event/ character were displayed) is now blank. Continue can be pressed in the corner and you can return to the main screen and will have gained the character, butr no rules have been applied to them.

Steps to Reproduce

1. Using Customer getter in Rules assistant create a rule which is dependant on "context.slave.custom.aiPrompts".
2. Aquire new slave and have the rules be applied to them.
3. OR disable prompt customisation on a slave, then apply the rules to them.

I have been able to fix this now. I changed the condition in the custom getter to check if the prompts are null. context => (context.slave.custom.aiPrompts != null) && (typeof value === 'string' ||context.slave.custom.aiPrompts.positive.includes("blonde hair"))
