Mouse problem in all modes

I got this package-pickup-quest from Rose and went to Wahoo-Beach to get it. The package is sitting on top of the counter but I just can't pick it up. (I tried clicking on/next to/above/under the package in addition to moving my character's position, as well as zooming the camera in and out several times but nothing works. Talking to Kishan doesn't help - neither does restarting the game.) Package is there Quest

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.
