Steam [resolved] Spoorlijn Groningen - Zwolle Missing After Today's Update.

After today's update on 31-04 my DLC route Groningen - Zwolle is not appearing anymore!

Things i've tried:
-Reinstalling the whole game
-Reinstalling the DLC alone
-Checked the DLC map in the steamapp files, it's still there.
-Integrity files checked on steam

 

Fixed: Cause was a CAF-logo mod. Still new to modding and didn't know it would cause trouble after updates!
After deleting it, it appeared again.

 

Mods can cause all kinds of issues, but which mod, and can you please post the link to it?
