Non-Forge

No, it exactly does not mean that. Select a different game directory for separate versions.

So does this mean I have to change the mods in my mods folder every time I switch between Forge 1.14 and 1.16 for example?

Thanks for the help!

1.12 is no longer supported on this forum. Please update to a modern version of Minecraft to receive support.

I'm using the ClientDisconnectionFromServerEvent event to listen for any disconnection. I am only interested in getting disconnections that happened due to errors (time out, etc.). This listens for every disconnection including the ones triggered by the player. How can I either only catch the errors that are thrown, or check for the reason?   Thank you.
