*Warning!* This could just be a coincidence but completing ACT-18/unlocking Iris caused my game to freeze. The music was still working but the game was unresponsive, I ended up having to forcefully close it. Luckily my data was fine!

It could be the new servant or dozens of new missions being unlocked at the same.
