Hello, about two or three weeks ago, i updated the game, and all of my ships are gone, has anyone experienced something similar?
Cosmoteer will not delete ships or saved games when upgrading. Chances are something else moved or deleted the files, or perhaps the location of your Documents folder changed or you're playing under a different user account, or something like that. I recommend searching your computer for files ending in .ship.png and hopefully that will find them. (I've never heard of a case where missing files were caused by Cosmoteer itself and not something else.)
