Wcl - All Going Normally, Until... What??

All well until very weird mastery reward by rivet. Though wcl isn't normal due to not being able to sit down on mk2as which is a pain.

 

Oh it's a mastery reward? I had no idea and it actually jump-scared me... talk about the unexpected!
I've had the route since it came out, and driven plenty of services, but never saw this in-game or mention of it on the forum

 

This has been reported to and noted by DTG, when we'll actually see a fix for this however..........
