Are you using an AI mod?

@Noah_Lukas yes boss I'm using.

And this is causing the problem. If too much AI is in this area everything gets messed up.
Try with ProMods only and if you still having problems with this roundabout, then fill out a proper Bug Report metioned as here: https://promods.net/viewtopic.php?f=29&t=939
You're report need coordinates. In The title the country and the ProMods Version you're using.

@Trucker2223 I can't find that coordinates sorry , I have seen many place like that bug.

I'm sure someone is encounter like this problem, maybe they are reporting this

To be honest there isn't any report like that, so it must be one of your mods.

Yes he's using an AI mod and it's probably the mod which is causing that bug.
