Don't worry about "the end of Among Us". We are not ending Among Us. But we are moving on to create new games. There are just three of us making Among Us, and we can't work on it forever, but we want you all to keep playing as long as you want to.
"Forcibly disconnected from the server" and "Reliable Packets" are errors, not crashes. Sometimes player connections are at fault, but I will try to reduce these problems while I'm still updating Among Us.
We will keep the servers running normally until at least 2021. It's hard to promise longer than that, but we will likely run them longer than that. We will announce if we are stopping the servers and provide some alternative.
The servers sometimes have issues. I have fixed it this time, and I will always attempt to fix it as fast as I can.
