Hi Joedaddy86,
Welcome to the forums. I’m sorry to hear this issue has affected your save also and I appreciate you taking the time to share the details of your experience as well as feedback. I completely understand that you would be very disappointed, especially when close to the last boss.
I am also sorry to hear that the potential workaround did not have an affect on you accessing your save.
The team are continuing to work on this issue to resolve it as quickly as possible and if I recieve any updates from them I’ll post it in - [Known Issue][* v.2104 *] "Continue" option for save not displaying in main menu - which I believe you’ve already posted in.
