Now I want to know why it crashes!
It somehow clips with a texture under the floors that nobody knows why it’s there, all they know is the game doesn’t work if they remove the texture. Something like that, probably.
We should boot the old 'blivion and figure it out
To be fair, most innocuous behavior makes Oblivion crash.
Salmo has two AI packages commanding him to take five loaves of bread to the Two Sisters Lodge at 10am and to the West Weald Inn at midday, but the packages never execute as he has no bread in his inventory and the packages are of “escort” type, meaning he doesn’t actively seek any out. It’s possible this bug was introduced to avoid another, more serious one: if bread is given to Salmo using the console or CS, he will walk to one of the inns as commanded, take a bite of bread, and the game will crash. (UESP)
Right, this is classic Bethesda stuff right here.
