It's in AAA games too. For example, Diablo 4 has incredibly degraded. Basic features are often broken, like dungeon exits sending you to the right locations, UI interfaces having things that can't be clicked under certain circumstances, unlockable season abilities simply not working, etc
But be wary of possible observation bias though. In my opinion, for one, the quality decline was going on long before AI.
AI could have amplified it.
On the contrary: software quality was steady and improving in my observations back then.
