Description

@0xalexbel

It's very hard to spot.

    function callbackDecryptMultipleValues(
        uint256 requestID,
        bool decryptedBool,
        uint32 decryptedUint32,
        uint32 decryptedUint64, // this is hard to spot the error here! uint32 is wrong, should be uint64
        bytes[] memory signatures
    ) external {
        FHE.checkSignatures(requestID, signatures);
        _clearBool = decryptedBool;
        _clearUint32 = decryptedUint32;
        _clearUint64 = decryptedUint64;
    }
