Unmerge Super Mario Bros. 2 and Super Mario Bros.: The Lost Levels
Twitch on January 12th merged the categories for Super Mario Bros.: The Lost Levels and Super Mario Bros. 2.
These are completely separate games with completely separate gameplay, streamers, and audiences. The merging seems to be done by mistake as they both share similarities in their naming variants, Super Mario Bros.: The Lost Levels often called Super Mario Bros. 2 (Japan) as it was the original sequel released in Japan only.
On IGDB, both Super Mario Bros.: The Lost Levels and Super Mario Bros. 2 have separate categories, so this seems to have been done via manual intervention on Twitch staff's side. Please correct this error otherwise these communities can see significant negative impact.
