Title is enough said. And it’s annoying. 
I bet the mods would fix this in B1419, right?
There should be a log.txt file in your automation folder, please post that along with more details for better and quicker help with your problem.
I’ll post recently what happened.

Scratch that. All cars.
Please post the whole thing, as well as the KeeEngineLog.
It’s really not! 
At what point is this happening, (what screen are you on, what are you doing, what did you just click on etc.)
