4.6 does crash less, I think I fixed it in 4.7 but we'll see when it gets released and other people can test it. But it only happens on the main world, so you can stick to dungeons and it shouldn't happen
You can also try only having a single save, and ensure it's "save0.sav". This has been a strange bug that plagued me only in 4.4 and trying different things produced strange results.
