i had this happen maybe 10% of the missions i run in Cambion Drift
usually happens in vaults with the extraction tentacle thing or with arcwing happens solo or in squad
i usually assume these thing will get solved but its really upsetting to happen when on the third Isolation Vault and restarting the game with no saved progress or items.
I have a similar issue with the Orb Vallis but the crash rate in that map is ridiculous (40%ish) can even run a mission
It really sucks feeling like i wasted time and money
