-Doors on [Beach] designated lots do not work as initially intended on previous lots. They do not open, nor can they close.

-[Vampires] cannot enter or exit certain [Beach] areas via [Fly Here As A Bat].

They could not land on a pier (in water) connected foundation, or the building on top of it.

I was building a beach resort style of [Beach] lot, when I found that indoor building locations do not function properly, such as a "bathroom," "bedroom," or just an empty room.

I've even noticed that vampires cannot fly onto porches.

This is troubling, as I'd like to purchase the Magic pack in order for my sims to be able to fly in to that porch location on a broomstick, and actually enter the building.

I may not purchase the Magic pack after all, especially since my Vampire sims cannot land on open air platforms in areas unconnected by stairs.

Again, no mods or cc were used. Buildings used is shown as attached below.

Previously reported through the forums:

I had to play through an adoption event where no one shows up to take the cat away, but the event never ended.
I couldn't save or go to manage worlds, so I had to kill off Cassandra Goth after the cat had ran away and it was found again.
That, unfortunately, did nothing to solve the problem.
(I forgot to mention that there were three cats, but one of the three had previously been through the adoption event before the second one.)
Both events involved a sim leaving the plot, and the game did not register it as over or cancelled.
Death reaped her, the "Game Over" screen showed up, Cassandra Goth and all two cats were no longer available as icons or characters to select.
I was also stuck on that same plot, unable to build or pretty much do anything to create a sim or solve the infinite event glitch.
I was forced with no other menu options but to exit to the main menu.
Manage Worlds was still unavailable, so I think this is a coding problem on your end.
No mods or CC were used, just the packs on hand.
