[2019] Solo-Co-op Disaster

Hey there @Renrij

Sorry to hear that. Have you checked your event log and see what happened? Also, are you using any mods in your game?
In any case, you should have a few backups of your save game located in your game instalation folder \ConanSandbox\Saved called “game_backup_x.db” which you could use to roll back to a previous state in which this didn’t happen. Just rename any of those backups to just “game.db”.

Mods can sometimes cause issues like this one when a patch is released and they’ve not been updated to be compliant with it.
Please make sure to keep them as updated as possible, and disable any that could be interfering with normal gameplay.
