Thanks for confirming that information for me @Adeis and @Loeckiey
From what I can see of the devs updates on this issue, they know what caused it and are now working on a fix for the issue. Unfortunately no workarounds have been found for this issue so far.
I’ve created a Known Issues report for this here: [Known Issue][* v.2104 *] "Continue" option for save not displaying in main menu and will update it with any additional information I recieve about either workarounds or the progress of the fix the team are working on.
