Playing with all the factions at the same time is your problem. Sins cannot handle having all six factions loaded at once that well; it is bound to cause minidumps mid/late game. Unless you lower all your graphics settings to lowest, and even then, Sins may still crash. Load up less factions, and suddenly you will find that the crashes will go away. The game does run out of memory; it's hitting the 2 GB limit. Whether you have 4, 6, 8+ GB doesn't matter with Sins if you are on Windows. Also make sure you have a paging file for the partition Sins is on. The only way to make full use of your RAM is to play Sins on Linux via WINE. To copy paste from the read-me I have for the next public release: Q. I don't understand why installing this mod is so complex. Why did you split off the factions? A. Due to how Windows handles 32-bit applications, Sins is limited to 2GB of RAM on all Windows machines. SoGE, with all factions enabled, has a tendancy to hit that limit, resulting in minidumps/crashes. By not enabling factions you aren't playing with, you reduce the amount of stuff loaded into memory, and thus help keep that 2GB monster at bay.
