Great ! :)
Thank you for your help !

Yes, it's working now! Thanks for updating :)

Is it working ?

Ok so I've gone ahead and made a custom thumbnail and tooltip image for this. I've named the file exactly how your currently have it so no one will have issues who have already subscribed. I changed the main image to look exactly the same as you have it here only I added a +Custom Thumbnail in white text.

All you have to do is download the .crp file here...

Then to update, Subscribe to this intersection and open up Cities Skylines, go to the content manager then assets and find your intersection and click update. Then a popup should come up and there will be a tiny folder in the bottom right hand corner of the preview image. Open that folder, then open the content folder. There you will see your old .crp file. remove it to your desktop if you wish to save/back it up. Then place my new .crp file in that content folder. Now you can go ahead and click update and it will overwrite the file on the steamworkshop and everything will be good to go.

Quick note before doing the update though, make sure to copy the description on the workshop page first because the update will erase it, then you can just paste it back and save.

This should only take you literally less than 2 mins to complete.
Hope you will update this! Thanks :)

Yes

C:\Users\Yourname\AppData\Local\Colossal Order\Cities_Skylines\Addons\Assets

Look for your .crp file there.

Do you know what the folder where I can find it is ?

If you message me the file I will update it for you and send the file back to you so you all you have to do is update it. :) All you would need to do is upload to http://www.tinyupload.com/ and give me the link. and I'll give you a new updated file link when im done.

Yeah I'll do this for sure but I can't work on my assets right now. I have exams for the next 4 weeks so I'll do it during this summer.

Thaz, Anyway you could update this with a preview thumbnail?
