Certain save failing in engine restart.
So I am now 3,500 hours into a project and have just started encountering a pretty scary problem.
I have a save that works just fine in editor (multiple tries of using games save and quit function/just hitting escape to exit PIE) but when I restart the engine, it seems corrupted or not loading.
Now for some clarification, the way that my project has been set up, I have 3 separate saves. We'll say "dungeon save, "meta save" and a "party save". The only one that has been altered since seeing this change is one variable in the meta save. Yet the one that seems to be "corrupted" is the party save. A save system that has been untouched for well over a month. This leads me to believe that it is likely not my code, but we have all been there and all been wrong.
Has anyone else encountered something like this that can provide some insight? I have deleted saved, intermediate and cache. I have restarted my system and verified install and I am now in the process of packaging to see if it persists there, though I assume it will as it happens in standalone.
Edit: the packaged build works as intended. It seems to only happen in editor.
