Its taken me a while to farm up all the keys so i could try ubers but just have a question. If you crash after opening portals do you lose them when you start your game back up?
If you are unable to rejoin the game you created the portals in, then yes, you will lose the portals.
Create a passworded game through the lobby. That way if you do crash, you can rejoin the game with the credentials you created the game with. I believe the game will stay running for ~5 minutes after everyone disconnects.
And keep fingers crossed the queue time is less than 5 minutes 
Yea, i don’t know how long it stays perm’d, but it definitely perms the games instantly. That’s one nice thing at least 'eh.
Well it was about 5 minutes on the original games bnet platform. I have not yet tested it since I no longer need to use the old solo way of muling. 
I’m positive that I’ve seen others say that it does stay running for a few minutes after everyone leaves in D2:R.
ok thats a great idea. ill do that
Yea, but it also took about 5 minutes to get perm’d on the old server, iir. Could be annoying. And yea, i haven’t had a need for mules at all myself, so, all good.
This was changed in the original game to perm instantly back in 2018ish I believe.
I picked up playing the OG in 2017 when I caught wind that Blizzard finally put a lid on the massive chat spammers… Which seems to have “resurrected” in D2:R. 
Oh? Haha, goes to show how long it’s been since i needed mules or perm’d games, lol. Its been awhile. Played last ladder before release, don’t recall doing it then either, i don’t think.
Well, there ya go, if it is so.
