How do I fix missing co-op inventory or wiped progress?

Update 6 targets client inventory loading, quest restoration and cases where multiplayer progress was wiped.

Quick answer

Install Update 6 or later before loading the co-op session again. NerveLabs says Update 6 fixed clients not loading inventory or restoring quest state, fixed cases of multiplayer progress being wiped and made co-op quests track to the host. The notes do not promise that already-lost data will be reconstructed.

Early Access note: this page is verified for Early Access Update 7; mechanics, locations and commands may change in later updates.

Steps

  1. Have the host and clients update to Update 6 or later.
  2. Load the host's intended save and rejoin with the affected client character.
  3. Check the client's inventory and quest tab after the updated session finishes loading.
  4. If data is still missing, report the build, host save and client state to NerveLabs; do not overwrite backups based on an unverified recovery trick.

Requirements / limits

  • Update 6 states that co-op quests track to the host.
  • The changelog does not document a manual recovery procedure for an already-damaged save.
  • No cited developer source guarantees retroactive restoration of data already lost before the patch.

Common mistakes

  • Having only the host update while a client remains on an older build.
  • Treating a client quest tab as the authority when Update 6 assigns co-op quest tracking to the host.
  • Claiming the patch can recover every older lost item or quest state.
