Solved Why can't I open the Traffic Lights window????????

Why can't I open the Traffic Lights window? Every time I click on it, it pops up for 1 millisecond then it's gone

 

Pls help me find why

 

It's hard to say without any further informations. But can I shoot from the hip?
The map you are in is not a vanilla map and the name of the map has some unwanted characters like "_äöü" or idk. The behaviour changed in one of the updates.

• Check if the problem stays, when you're in a vanilla map.
• Give us the (folder-)name of the map where the problem occours
• If that's the problem use AlexKidd71's Tool to rename the map

Hope that helps

 

I will send you a video of the problem in a couple of minutes

 

To confirm my theory, it is enough if you tell me the name of the map. Preferably the name of the map folder.

 

The error message describes where the error happens, unfortunately not why.

 

It's on everymaps, not just only one, but all of them
