15 bots are back.
Setting update has been deployed:
https://github.com/triplea-game/infrastructure/commit/54f11b2da26c9b9a7a18079a0489fdc76dc2c756
The act of deploying an update would have booted the missing bots. They would have been crash/disconnected due to something within our control (system config, code issues, something we own).
I don't know if that setting will have an impact on the lobby bots. I do see that they are not full on restarting when a game is over, that seems more stable.
The restart of lobby bots was otherwise handled by systemctl rather than docker. Maybe a key difference, maybe not, I'm not sure.
I'll be interested if bots drop off again.
