SH3D is eating memory.
When it has used about ninetyfive percent of your available memory, it will freeze or crash.
My trick is to have the Activity Monitor running, and watching my memory usage.
When I'm about to run out of memory, I save and quit.
After I restart SH3D, my memory usage is back to normal for a while.
The more memory you have, the longer the intervals.
