Network error when sending AI Attack Ping, despite not being a MP game

I’ve noticed sometimes when sending an Attack ping on a local AI game (so not multiplayer), it will pop up with a network error as if I was playing MP. I’m not even sure if the attack ping is even working, because it doesn’t seem to do anything. The error doesn’t always show up when I ping, and often it will only show up 5-6 seconds later.

Same here
I think this will be fixed soon.
