I have had issues with Buildbox crashing (An unexpected error occured), and when I re-open it, I have a choice to load the previous session. However this never works, and I end up having to do all the work over again from the previous saved file. Is there a fix for this? Or do I just have to start saving after each level i make? What are your methods on working with the crashes? Or does this only occur to me? Please share your experiences so we can hopefully get rid of this VERY annoying problem!
