Well I cant get in to Sh4 to well atm, since nearly every career I make ends up corrupted. Ive got as far as summer '43 and thats about it. I have been taking the utmost caution in saving, using multiple files, keeping backups in the captains room, etc etc. but gauranteed I get a corrupted game.
I have had the game less than a month and its starting to wear thin on the restarts, in total I've started 8 careers, and it would be nice to actually be able to play one without corruption. I keep getting strange occurances in the game that usually points towards the game being busted. Things like when I load a game at sea I hear the WO call "torpedo in the water" but there are no fish running. Or I hear the message "passing thermal layer" every 30 seconds, even on the surface

.Ive got one save game in the captains room thats gauranteed to make any and all saves at sea with it corrupted, regardless of what I try.
Ive get it with un-modded games, and modded alike. There is no reason to it, except that its usually after spring '42 when it happens. I know my rig to be in perfect working order, and the system is bang up to date with everything software related. Its not a cutting edge rig but it is very easily capable of running SH4 maxed out.
Does anyone know what might be causing it and what can be done about this? Is there known conflicting software with the game? Are there any tools to backup or recover save files? Is there any tweaks I can make to the game to help? Do any mods have a fix for this?
Im at my wits end almost, and I need some advice.
