[GAMEPLAY]? Ingame chat spamming control ward bought by no one

If that image doesnt work I'll reput it here in an imgur but it was periodically spamming "() purchased control ward" for a good portion of the game, even when no one was in base.

I have no idea how it occurred or how to recreate it, but this is the first time I've seen it happen. I figured I'd mention it cause it was just weird.
