string.date.parse does not work on cyclic objects

Hello, i did not find anything related to this, but if i have a cyclic type like this: 
export const types = scope({
    User: {
        "id": "number",
        "supervisor": "User"
        "createdAt": "string.date.parse"
    }
})
export const types = scope({
    User: {
        "id": "number",
        "supervisor": "User"
        "createdAt": "string.date.parse"
    }
})
if i try to parse it like: 
const user = types.User(data)
const user = types.User(data)
then only the createdAt of the user itself gets a Date, but user.supervisor.createdAt stays a string. how can i fix this? thanks a lot!

Hmm if that's occuring it sounds like it could be a bug. Could you post a full repro, potentially using the playground? https://arktype.io/playground I tried the following but it seemed to have as expected: 
import { scope } from "arktype"

export const types = scope({
    User: {
        id: "number",
        "supervisor?": "User",
        createdAt: "string.date.parse"
    }
}).export()

const data = types.User({
    id: 5,
    supervisor: {
        id: 7,
        createdAt: "0"
    },
    createdAt: "1"
})

console.log(data)
import { scope } from "arktype"

export const types = scope({
    User: {
        id: "number",
        "supervisor?": "User",
        createdAt: "string.date.parse"
    }
}).export()

const data = types.User({
    id: 5,
    supervisor: {
        id: 7,
        createdAt: "0"
    },
    createdAt: "1"
})

console.log(data)

indeed your example works. but i found if the type of supervisor is "User | null" then it does not. https://arktype.io/playground?code=import%2520%257B%2520type%252C%2520scope%2520%257D%2520from%2520%2522arktype%2522%250A%250Aexport%2520const%2520types%2520%253D%2520scope%28%257B%250A%2520%2520%2520%2520User%253A%2520%257B%250A%2520%2520%2520%2520%2520%2520%2520%2520%2522id%253F%2522%253A%2520%2522number%2520%257C%2520null%2522%252C%250A%2520%2520%2520%2520%2520%2520%2520%2520%2522supervisor%253F%2522%253A%2520%2522User%2520%257C%2520null%2522%252C%250A%2520%2520%2520%2520%2520%2520%2520%2520%2522lastUpdate%253F%2522%253A%2520%2522string.date.parse%2522%252C%250A%2520%2520%2520%2520%257D%250A%250A%257D%29.export%28%29%250A%250Aconst%2520out%2520%253D%2520types.User%28%257B%250A%2520%2520%2520%2520id%253A%25207%252C%250A%2520%2520%2520%2520supervisor%253A%2520%257B%250A%2520%2520%2520%2520%2520%2520%2520%2520id%253A%25207%252C%250A%2520%2520%2520%2520%2520%2520%2520%2520lastUpdate%253A%2520%25221%2522%250A%2520%2520%2520%2520%257D%252C%250A%2520%2520%2520%2520lastUpdate%253A%2520%25220%2522%250A%257D%29%250A%250Aconsole.log%28out%29%250A%250A

Yeah this is definitely wrong, thanks for the follow up. Can you log a github issue with this repro so we can track fixing it?
