In my copy of London Dread I found two extra card packs - one to correct the different back shading of ~20 cards and one with some corrected plot cards (some originals were missing the "time of day" icon).
Check your box if you missed those packs (each of them had one card with descriptions on what to replace).
If you can't find those - contact Grey Fox...
We did find the corrected plot cards to include the time of day. I'll have him check again for the corrected shading cards. Thanks!
