You can claim for any reasonable expenses that results from the delayed luggage. Now if you are returning home then there's an expectation that you won't be able to claim anything, but given the next flight, I would nevertheless claim for any bits of pieces you need to get as result of being separated from some of your possessions.

But the core message above is correct: ensure your details are in Worldtracer then get on with your life. The only thing I would suggest is doing an inventory of what was in the bag, on the basis it may be easier to recall what you packed. Hopefully it will only serve as a checklist that all the contents are returned to you.
