I just deployed my app with bluegreen deployment, there was an old machine running from 2 months ago in a different region, the deployment left that machine there in a stopped state, which has an older image version.
I tried making many requests to see if Fly would route requests to it, it seems it does, the machine was previously stopped and after some load it was running. Now i destroyed it.
This is very dangerous because different app versions are not guaranteed to work together well.
The app is called websocket-preview, the deployment with this issue is v116
