Analyze scheduling fails after removing activity from plan

Checked for duplicates

No - I haven't checked

Is this a regression?

Yes - This worked in a previous version

Version

Describe the bug

Running "analyze scheduling" after removing an activity from the plan results in an error.

Reproduction

1. Run scheduling goals (goal I used is below)
2. Delete some of the activity directives created by the scheduler
3. Run "analyze" scheduling
4. Fails with error (see log)

I used this scheduling goal:

export default (): Goal => {
    return Goal.ActivityRecurrenceGoal({ interval: Temporal.Duration.from({hours: 6}), activityTemplate:ActivityTemplates.AVS_BDS_or_EMEM_NAND_Power_Cycle({bds_emem: 'BOTH'})})
}
