Hello, I came to ask about using Mii fighters online.
So I used this mod:
https://gbatemp.net/threads/smash-4-easy-css-editor.428542/ to get the standalone Miis on the CSS so I could play as them online. (Yes, the mii being used IS default medium sized so normally no problems should happen due to sizing).
Installed it and booted mods on my wii u and it worked fine. The only problem was using them online, because whenever I get into a match, a few seconds in I'll get the "An error has occurred" error message and I'm sent back to the with friends/with anyone online screen. I tested this out with the enemy Miis (the ones in multi-man smash) as well. It's a little different in their case because every time the match starts, the opponent immediately disconnects and I'm facing a CPU.
Could I get some help on why I'm getting this error message and how I could prevent it from happening? Really, I only want help on figuring out how to get the standalone Miis to work, not the enemy Miis. I could care less about those. Could it be something with other miis on my system (that have various sizes) appearing in place of the Nintendo Network mii appearing on my screen, or could it have something to do with the other players' Miis?
