In the Diving for Arns quest in Hlan Oek, you need to put 10 rusty dwemer cogs into a crate. After that, your journal should be updated to another stage.

If you're using OpenMW Animated Containers, there's a slight issue with the journal update. Normally, the journal should open immediately once you exit the inventory menu. With the mod, you have to open the crate again to trigger the journal update. See: https://discord.com/channels/132891272666021888/662651493794447385/1169156969463033856

This is probably caused by some difference in MenuMode timing between the vanilla and animated containers, but it should be fixable by adjusting the crate script a little.
