This doesn't look related to WPF. Transferring to the runtime...

        private void UpdateStatusReport()
        {
            StatusReport = $"Vault report:\n{HoneyVault.StatusReport}\n" +
            $"\nEgg count: {eggs:0.0}\nUnassigned workers: {unassignedWorkers:0.0}\n" +
            $"{WorkerStatus("Nectar Collector")}\n{WorkerStatus("Honey Manufacturer")}" +
            $"\n{WorkerStatus("Egg Care")}\nTOTAL WORKERS: {workers.Length}";
        }
