Hello Zarkopfilis,
So, step me through what exactly you are experiencing. You are saying that your stationary lights are not working. What specifically are they doing that you are expecting? Are the lights not showing up at all or not behaving in the way that you would expect them to? If they are not working at all, step me through how you set them up and give me a screenshot of one of them inside of the Unreal Editor. If they are not behaving in a way that you would expect. Then I would try changing them to static and then re package after building the lighting.
Let me know what you find out.
Thanks,
