Yeah this is a better answer, makes sense. Obviously its possible. The way Yu-Gi-Oh works today between client and server is not magical. But I appreciate that code is not set up to support the game loop on a single machine and doing so would be a ton of work that probably isn’t worth the time and effort.
Manual mode is not a good suggestion :p. You guys really need to just disable that mode until you can actually make it functional. Its… embarrassing just how broken that mode is and if it were my product its absolutely not a state I’d be okay with having it in. And I say that with love.
