I was having a race on KY1 with AI and received these messages (see blue messages on attached picture and replay file).

The blue messages read:

ENTERED the pitlane for no purpose

and

ENTERED the pitlane for stop-go penalty

Stopngo is clear, they're just doing stopngo pens for speeding/jumpstart. dunno whats this no purpose though

How is the stop-go clear? It doesn't say who is having his stop-go. It just says ENTERED. But who!?

The ai "is" you, and so the game says you entered the pit.

I did not enter the pitlane or go serve a stop-go penalty.
