False cancellation email from Airline??? Has anybody experienced this before?

Hello, today I experienced something very strange. I have tickets through Expedia flying from the US to Belgrade Serbia flying Lufthansa. This morning I received a email from Lufthansa saying the last leg of my flight has been canceled. So I get on the phone and call Expedia, only for them to tell me that the flight is not canceled and to call Lufthansa to figure this out as my tickets are still good. Me, thinking that this is some third party fuckery and mentally preparing myself to be told to recall Expedia to tell them they are full of shit call Lufthansa. I explain the situation and give them my code for them to check my flights…. Only for the lady at the airline to tell me my flights have not been canceled and that me being sent a email saying that the last leg was canceled must be “some kind of mistake”. 🤨🤨

I still have the the email saying it’s canceled. Also, on the Lufthansa app, it says the last leg of my trip has been canceled on the app, yet I have been told by the airline themselves that it was a mistake and my tickets/the flight is still good. People of reddit, have any of y’all experienced something like this ever? Or should I mentally prepare for the mental anal fucking that might happen to my asshole if it turns out my flight actually is canceled and I need to reroute it?

Flight number- Lufthansa 1410 from Frankfurt to Belgrade
