i have, but only to a certain degree. adding blood is not a problem. but trying to change genes on your ship thats hard, all changes i try to make makes the game crash. and another issue that i have is that when i change the max support limit it works when the game starts but soon after that the game changes it back down to the real value
well, the shiplimits go back to normal when you do something that changes that figure. (ie. upgrades and going to a new level)
