ok, thanks! also, seems that because i left the tool alone for a while after crashing, it deleted the entire code. i think you should keep that in, but maybe make so that when you open the tool it will make a backup file, make you download your old progress without the () x () or a block that potentially crash the tool, and then you can resume from there. Maybe there could also be a detector for potential crashes that won't run the project but gives the person a warning.
