In episode 23 of the original series, Okabe receives a D-mail from 2025 which triggers him try again to save Kurisu and enter Steins Gate.
In episode of 23 of Steins;Gate 0 we see the same scene:
There's a clear discrepancy here. The year in the date.
The text "受信日時" translates to "Reception date and time".
- When receiving D-mails, which date is supposed to be used? The sending world line's date? Or the receiving world line's date? Normally, this doesn't matter since the send and receive dates will be almost the same for electronic communication.
- Is this discrepancy intentional? Or is it a goof? If it is intentional, is there yet another world line change hidden underneath that we don't know yet? (The ending of Steins;Gate 0 left plenty of room for a 3rd season.)
