I have the same issue :). And since asset can be removed : must have a better solution :)

Ok, I need more details about how to reproduce.

"This is a path to a temp folder. The file may be deleted. "

It's generated via the asset manager, so if the tmp file is deleted, a new one is created and the path "should" be updated.

@LouisGac : if you save current asset url for picture,

But reset asset version number a lot of time : i think old asset url become invalid (and the not recreated)

And currently : something happen in my test system

1. Last week i upload a picture
2. Set this picture in the list, select it
3. reset asset version number 5 times (in global settings)
4. this week : my won logo was replaced by default

It's hard to reproduce, because it take times (and TemplateConfig have some auto repair system).

Adding a image with ./files/myfile.png work better :) .

@LouisGac : i can confirm : after some day : assets directory is removed … the no logo

thank you Denis

PS : on forum : seems not exactly the same issue … :/
