I'm currently playing Steins;Gate My Darling's embrace and I feel like there's a weird plot hole here.
Okabe sends a d-mail to avoid sending another d-mail but he's already in a different timeline so that shouldn't work. That d-mail later appears in the sent and received section of the phone (even though it should only appear on received since he didn't send it on this timeline).
This was a huge plot point in the original story so I find this change in logic extremely fucking weird. >inb4 who cares Kurisu sex
