What's strange is the fact that Grimjoww08 is saying the container disappeared on all their save files, not just the most recent; that makes it sound like it could be some kind of change in a patch which has caused that container to no longer be recognised by the game, e.g- it could be too full as they say, maybe that specific container no longer exists in the game, maybe the method of referencing the container as an inventory asset no longer works the same way, or maybe it contained something the game doesn't like?
You might try reverting the game to the previous version, but you'll need to find up to date instructions on how to do that (been a long time since I've done it using Steam). However if the previous version shows your items as expected, then it would confirm this as a regression.
