Saving your Work
It's important that you set up the editor to save your work, as for some unknown reason cryengine always has a tendency to crash at the wrong times. For that fact, just about all Game editors crash for one reason or another. You can set the editor to AutoSave or to Remind you to Save. Either of these options allows you to set whatever time works for you. Note on using the Remind To Save - When it does pop up on the screen save your before time comes for it to remind you again or it may mess up a bit.
