ganache-time-traveler not working with Ganache 7.3.1 - Is there a fix??

[msuscens]

Hello,

I have Truffle tests that successfully pass with Ganache v6 but fail with Ganache v7.3.1. The truffle tests in question use the ganache-time-traveler utility to advance time. Specifically, the issue is with functions that need a certain amount of time to pass before they will execute (without reverting). I, therefore, use ganache-time-traveler to advance the time before executing the function. Unfortunately, with ganache 7.3.1 these functions revert even though time has been advanced by the required amount. Here is an example:

describe("After Incubation: Hatch single egg", () => {

        let snapshotId
        beforeEach("Advance Time to End of Incubation", async() => {
            let snapshot = await timeMachine.takeSnapshot()
            snapshotId = snapshot['result']

            // Incubate for required time
            await truffleAssert.passes(
                timeMachine.advanceTimeAndBlock(INCUBATION_DURATION),
                "Failed to advance time and block"
            )
        })

        afterEach("Revert To Start of Incubation Time", async() => {
            await timeMachine.revertToSnapshot(snapshotId)
        })

        it("should allow egg owner to hatch it, emitting an Hatched event ", async () => {
            let txResult
            await truffleAssert.passes(
                txResult = await eggToken.hatch(
                    [0], //eggids
                    {from: accounts[2]}
                )
            )
            truffleAssert.eventEmitted(txResult, 'Hatched', (ev) => {
                return equals(toNumbers(ev.hatchlingIds), [0]) &&
                    equals(toNumbers(ev.eggIds),[0]) &&
                    ev.owner == accounts[2]
            }, "Event Hatched has incorrect parameter values!")
        })

etc ...

This test passes with Ganche v6 but eggToken.hatch reverts under v7.3.1 with the following message:

After Incubation: Hatch single egg
         should allow egg owner to hatch it, emitting an Hatched event :
     Transaction: 0x20883a2a3329b9925a86499b4fe1e9727a029f197d00f084ed920e94eb1954d6 exited with an error (status 0). Reason given: hatch: Egg not incubated!.
     Please check that the transaction:
     - satisfies all conditions set by Solidity `require` statements.
     - does not trigger a Solidity `revert` statement.

Is this a known issue and/or is there a workaround? I'd appreciate any help/advice on how to resolve this issue.

I'm on a 2022 MacBook Pro (M1 Pro processor).
Truffle v5.5.3 (core: 5.5.3)
Ganache v7.0.1
Solidity - 0.8.13 (solc-js)
Node v14.15.5
Web3.js v1.5.3

Note: Even though it says "Ganache v7.0.1" above (from 'truffle version'), I've installed v7.3.1 and when I start ganache (via CL) it says "ganache v7.3.1 (@ganache/cli: 0.4.1, @ganache/core: 0.4.1)"

Ok I’ve opened an issue: #3265
