Started up a Solo world for the DW20 pack the other day, crated the world the pack was at 5.0.1 so it's the latest and current build. Can back to it today and when I tried going into the (over) world I would get the MC has crashed screen with an error message. I tried again and got in. Went to the nether for about an hour, but when I tried to go back to the overworld I got the same crash. All I have in my overworld so far is very basic machines like IC2 furnace/mac/extractor and the Thaumcraft table/research thing.
Here's the error:
