I think you might have to open the Chat box and select AI Commands on the right, and then do “104” from there (see screenshot). It seems to work for me more often than not when I do that. I want to say it always works, but I think there’s been a few times where it hasn’t; I could be wrong.
I wish you didn’t have to go here… but it seems a lot more reliable using this method. I wish you could just send “Everyone” the “104”, but alas.
I also wish it was a setting you could specify in the lobby, at least for when playing with AI opponents and teammates. I always forget after a match starts. And then after I start destroying the AI, I remember about the 104 thing, and hurriedly try to do the AI Command ‘104’, only to have the AI resign literally 1 or 2 seconds before I’m able to execute the command… and they have a bunch of buildings and units left standing. That’s happened to me at least 5 to 10 times now. As a completionist type of player, it’s a bummer.
