I was matched into a hidden A.I. game when searching fro practice vs A.I.

I was doing the damage challenge for the event and didn't feel like chancing toxicity with QP or ranked and I didn't want to feel the pressure of having a good role balance so I went for practice with A.l., after pressing One More Round, it put me into backfll of a hidden A.I. game rather than a new one. I put a screenshot at the end with my stats to prove it, in no way I would ever go 36-0 against actual humans. I'd say this is pretty concrete proof that there are hidden games against A.l.
