I get why you would want that, but I think that would end up causing other weird issues. Like what happens when someone from that instance is in the middle of a comment chain? Would it cut off the thread there, or would there just be a comment missing?
I’ll take the simple solution over no solution.
That’s a major part in the Ender’s Game series. They have faster than light communication, but the ships travel at like 90% the speed of light. So when traveling between planets, it’s like a two week trip to the people traveling, but 20 years on planet.
The main character Ender travels often, so he is only 35 in the second book, a couple thousand years after the first book.
