After completing the steps in Part 14 of Crash Course 2 I hit the Save Game button and got an error, when I clicked the Details button I got the following information:

Do you get this error each time you save, or is it random?

It has only happened once so far and once I cleared the error message I was able to continue to use Stencyl and save.

I've now encountered the error about a half dozen times, always when saving and always I can just clear the error message and hit save again and it works.

After getting this error about a dozen times I got another error message saying Stencyl was over 90% memory use and needs to be restarted.
