I got to step 4 but couldn't find a second .dat file so I changed the biggest one from the offzip to .dat and was able to load it in the editor. It's working fine right now and I'm able to play it, just wondering if that's something to be worried about and if I'll have problems with this save later on. I don't want to get somewhere and have to restart, I'm terrible at this game. Very confusing so thank you for the amazing editor
