I've just started a brand new project to quickly test some level design ideas with a bunch of basic 16x16x16 cubes, and I've got a few crashes, though not while using the script editor. So far it either was when saving the map, or when hiding/showing a group. I'm using an older computer (also with Windows 10) and I noticed it's quite slower to open models in the voxel editor, sometimes, 4-5 seconds, but otherwise I didn't see any major difference.
It's possibly a memory problem, since the crashes occured after a while using the editor, maybe 20-30 minutes. Now I think about it, I sometimes get similar crashes on my main computer (which is less than one year old and more powerful), but way less often.
