Problem
I have an online league (for testing purposes), and have added some custom CSS in the league options.
To test out my custom CSS, I developed it offline, by manually copying the file (using FTP) to the league 'Styles' folder on my site.
When I hit the "upload" button, however, only the default CSS is coped.
This happens *every* time I hit the "upload" button (I can see the date of the file on the server changing).
Investigation
Looking at the "HTML\Styles" folder under "DDS PF21" in my documents folder, I see that this isn't being updated, but if I update it manually, then these modifications *do* get uploaded.
Conclusions
This behaviour would lead me to believe that the changes I make on the "Custom CSS" tab in-game are not being written to the hard disk.
Is this, perhaps, because my user folders are on a network drive?
