This might answer your question, V'klya, and it may be considered a genuine bug also.
If you are wearing a container and there is a similar one on the floor, take a cloak for example, and you examine the cloak, you will be returned the description of the cloak you are wearing and the contents of the cloak on the ground. Very strange.
For example, watch what happens when I enter a room with a black cloak, when I am wearing a blue cloak around my body.

The description should be shown here, but it is not, since the black cloak is not a container.

Had I examined 'blue' and not cloak, I would have seen the desc and contents of the blue cloak, but if the keyword cloak is used, then the desc of the item you are wearing is shown
but with the contents of the item on the ground.
The reason that it may have seemed like it took a couple of hours for your containers to 'fix' themselves could be that you were carrying a container in your inventory that carried the same keyword as the one you were wearing. What gets confusing is if they are both containers.
The problem seems to be that the examine command checks your equipment first for descriptions, then checks the ground and your inventory first when it comes to contents of containers. It's very strange, and a real bug, I think.
