random crashes, anyway too help prevent?

i was editing a land scape for a game i was creating and i had a crash but even though i have multiple auto saves through the project i crashed, opened it up, and i was shocked at how far back it set me. Anyway i can help prevent this?

-which engine version do you use?
-could you post the crash log so that we can see why the engine crashed -> yourproject-saved-logs
-make sure to post your crashes on answerhub -> https://answers.unrealengine/ :slight_smile:

A good way to prevent such stuff is to always save your level + to use stable engine versions
