If crash occurs immediately after saving, the last save file is lost

If this is part of the engine, I guess we can't fix it (except for fixing the experimental engine). But it might just be the game script isn't writing out the save file count variable, and we just need to force it to update the `global.dat` immediately after it saves.

Note that I simulated crashing on Windows by ending the process via task manager.

Esamina la struttura della cartella di salvataggio e il file global.dat per capire come vengono registrati i salvataggi. Analizza lo script del gioco e il codice del motore per individuare dove vengono scritti i file di salvataggio e dove viene aggiornato global.dat. L'obiettivo è assicurarsi che global.dat venga aggiornato immediatamente dopo un salvataggio, non in seguito, per prevenire la perdita di dati in caso di crash.
