I started up Oblivion brand new with the 1.33 Complete Final of OOO a month or so ago and then I found version 1.34 beta 5. Everything I looked at says it should work fine over the top of my existing OOO load but it crashes to desktop the moment it tries to load my savegame. However starting a new game works fine with all the same mods. Is there a load order issue or do I need to use Wrye Bash?
