4: Not bug but suggestion - Have a "center on char" or "Center map" option in case you weren't paying attention and lost your camera in the void, it would allow you to get your camera position unlost
Use the Home key or double click on the leader's portrait to re-centre the screen focus. Switching leaders (by clicking portraits or using the F1-F4 hotkeys) will also re-centre the camera.
3 baskets on the docks blew up when I tried moving the item to an avatar icon. More specifically, the baskets near the 3 guys looking for work. The loot still came out, but it was very odd and weird.
I didn't have any problem with them. Opening a crate/basket/barrel and trying to place it into its own inventory window will destroy it, which may have been the effect you saw...
