This is driving me nuts. If I have Offline Ai traffic turned on I always get this annoying thing from ATC. Constantly repeating the same instructions to some AI traffic (this above is just an example), more often than not many different AI planes, that obviously have no intentions to follow ATC instructions. What’s happening here?

It’s a long known bug.
