I posted about this same issue 3 days ago, can I take this as confirmation that no-one at Obsidian is bothering to read what I'm posting?
We are a 10 person team working on this game, apologies for the delay.
We are working on a repro on this issue. Thanks for the additional data! @Limwik Ill take a look at your issue and see what is going on. @scmc872 Can you provide the full PFID? Tap the options to bring up the menu then go to settings at the very bottom you'll see VER and PFID, I need everything that follows the PFID. Thanks!
Are you able to start a new party? Also if you delete that saved party those characters will appear in your Experienced character Filter at the character selection screen and you'll be able to continue using the same party.
Thanks for reporting this, sorry it took us so long to get to it. We are looking into what went wrong now. Thanks for taking the time for such a detailed write up. These really help!
