Museum outside textures not showing

I just downloaded the new patch and started my game. After I entered the Furniture Store the screen went black for a split second and my character instantly wasn't able to move anymore. Camera-rotation (as well as zooming in/out) worked as usual. After some time passed the screen went black for a split second again and my character was finally able to move. Was there supposed to be your announced cutscene?

after opening 10-15 mails while having my backpack open and then leaving the mailbox my backpack became invisible, triggering the button caused the sound of opening a mail too but the backpack itself was invisible. saving and leaving to the menu and reentering fixed it for now.

I just got two delivery bags from Tanis but I didn't receive a quest attached to said bags. (No new delivery quest is shown in my journal.) I can hold them but there is no info showing up, wenn clicking on Info. So ... I don't know what to to with these objects.
