Get an older version of your model back Anylogic

Question

I've a question, I made some change in my model and probably did something wrong, but now every time I open my model, it crashes when I want to open something and I need to close anylogic.. So now I want to open an older version of the model, so that I can work further without having to use a backup of one week ago, is anylogic automaticaly saving some older copies of my model or not? If so where can i find these older versions.

Or is there a way to solve this problem. I deleted the type of the arraylist LiftpleinenPeds collection, and now everytime I click on the collection to change this, the whole anylogic crashes. I only need to change it in the main java to add node as shown in the image, but I am not able to modify something there?

You can open the AnyLogic file the '.alp' file inside any text editor. You can make your changes there (but be careful) and rather make a backup before you do this.

You can literally build your entire model in text mode if you want to ;-)
