I only entered 104 once in my last game. Then, once one of the AIs resigned, I probably spammed 104 twenty times out of frustration
Even if your theory was true, it shouldn’t be acting as a toggle where you click it once it turns it on, click it again turns it off, etc. There’s a completely separate command to re-allow AIs to resign… I think it’s 105; which is even more of a reason why 104 shouldn’t be some weird toggle.
Furthermore, having a chat confirmation as I proposed in that thread (assuming it’s actually functional and not just for show,), would be great confirmation of what the AI intend (or don’t intend to do)
