The minigames basically had the same issue, the resolution, but yes those are fixed, except the kitchen gift still softlocks the game when pressing on "nevermind".
The dialog loop is fixed already yes.
As for why is taking longer, more of the older cgs are getting reworked, some content is getting added, and some of the older minigames are getting some upgrades. So yes, 1.8B won't be an only bugfixes patch, kind of like how 1.5B got some content before.
