Let's simplify the process! If you can provide the following details when you get in touch with Support about items you lost from a dropped mission, they'll do everything they can:
- The lost reward that was most important to you, which you'd like to receive
- The alias or aliases of members in your squad
- Roughly the time and day you were playing
Support has been told about the crashes on Orb Vallis, so they'll know some extra help might be needed. I've edited my message above to keep everyone on the same page!
