Just had an extremely aggravating experience with carrara. I had have been working on a ninja model for a few weeks. Tonite i decided to do some more work on it. so anyways, im making a vertex model, I subdivide it, then save the file. I go into the placement room, examine it and decide i shouldn't sub it just yet so i undo a few times. Then, when i try to undo the sub, says "error occured will trying to complete operation" and the model is all chopped up and wierd looking. So i close that file w/o saving and open the previous save and carrara crashes while im loading it! so now i cant open the file at all! all that work i did is lost. It was a really great model too :( . this shit happen to anyone else? Izuel
