I am having the same issue trying to load the Belsavis orbital spaceport. I have tried the "Delete Bitraider" etc even tried using the installer to try fix it. But nothing I have done is working and the "Repair" option has been disabled due to the new "Patch" and I am unable to select it (Its greyed out. Logged in or not)
Kind of stops my progression on that character for now (my Main) as I play the storyline before moving on to the next.
EDIT - Ok I was able to fix the issue on my 3rd clean re-install of the game. But now im getting missing textures everywhere (The missing texture are even labeled as "Missing Textures" boxes 😕 )
