Size Limit?

I appreciate the offer mate. I got models and stuff pretty well covered. I am just having issues with the engine itself. Got a new issue where the engine randomly crashes inside my main map. There are no blue print errors. There is no over heating. New hard drive ram and GPU. New versions of windows (clean installs) Every other game and program runs at the highest settings. But unreal won’t even run stable on low. Its doing my head in. But what is weird is that after publishing my game I can play it fine for hours.
