First a rant: I mucked up a mission and didn't have quite enough delta V to re enter kerbin atmosphere. I decided to load an autosave. I don't normally use autosaves, but it's been a tough day and I wasn't prepared to repeat the entire mission. I had assumed the game autosaves whenever entering a new SOI or moving into a sub-orbital trajectory - it seems to do this some of the time but not all of the time. It loaded up an autosave from several weeks ago, undoing a signifiicant amount of progress. As soon as it loaded up this save I immediately Ctrl-Alt-del'd out and terminated the program but it was too late. My save is gone, i've checked. I particularly miss the space station I constructed. My suggestions are these: 1. Auto-save should be regular and more consistent - every time you enter a new SOI or enter/leave a sub-orbital trajectory. 2. Multiple stored Auto-saves. About 5 should be plenty. 3. Give the dates (both real world and in-game) and number of active missions in the selectable save file. These features should provide enough redundancy that a mistake like the one I made would be easily recovered from. It's also a pretty common feature in most modern games that feature a save system.
