I tried loading the new UPKs from the DLC5 folder in the Enhanced Edition directory in the editor and get a version error so it was possibly put together & cooked in a newer version of the editor 
edit: just replaced Firestone Colosium with Oasis and it works fine fast traveling to ‘Firestone Coloseum’…a few missing textures but all the mapslot fast travels seem to work.



. Also WT 2.3.0. edits gear in remastered saves alright.
