I saw posts addressing problems with Archive Invalidation not working but none of them mentioned anything resembling my issue. I have been playing New Vegas for weeks now using MO and archive invalidation has worked perfectly the entire time. Last week I set up a second profile to install DUST to, changed my mind after downloading it, never installed anything for it, and never ran the game using the DUST profile i created. I switched back to my default profile and ran the game as usual and my archive invalidation no longer works. I checked and rechecked the automatic archive invalidation, verified that my ini's are all writable, and made sure it wasn't just a load order issue. Everything is normal and from what i can tell it should be working?
