I used the save editor to tweak my town and made sure to avoid the common issues listed on the FAQ of the save editor. It normally works fine, but gives me a crash screen on loading the game after skipping the system date too far foward. Enabling game patching and switching the hb title to the current ap worked for a bit, then the crash returned shortly after. I've reloaded a backup save for now, but I'm concerned I'll run into the same problem again in the future if I don't figure out what exactly is the problem here, which is really demotivating when I've put a lot of hours into this save file. In a nutshell, the crashes seem random to me and I'm almost certain something in my edited save file is causing this, but I just can't pinpoint exactly what. I can provide the map data of my game if it helps!
