Which config file is Weather settings (inc. real-road) stored in?

I'm trying to run a second rf2 dedi-server instance on a shared server. It all works fine *except* that the Weather settings (in the 'Selected Events' tab) are not saved.

I believe it's a file-permission issue - I've had to grant write access to the Multiplayer.JSON, WelcomePlugin.JSON and player.JSON file in order to get this server instance to load and run - but can't work out which file the starting rubber, real-road multipliers, weather settings etc. are stored in - clearly I need to grant write access to this/these files too...

And no, I'd prefer not to crack the nut by granting Write to every file under the sun!

 

.wet for the weather
.rrbin for the rubber

Both found in \UserData\player\Settings\{TRACK NAME}

 

Excellent, thanks - that looks to have sorted it.
