Errors and fixes
Something broke? Pick what you see: mods not loading, crashes and matchmaking blocks, creator tool errors, broken skins, manager or Linux problems.
Pick the problem you see. Each guide puts the exact error text first, so you can match it to your screen. After a game update, start with the first two.
Playing with mods
Pick this if the game starts fine, but your skins, sounds, or icons do not show.
Pick this if you see a FATAL ERROR, the game closes at launch, or
matchmaking refuses to start.
Pick this if the app will not start, antivirus flags it, downloads get stuck, or it cannot find the game.
Pick this if you cannot find the game folder, or the mod manager window stays grey. Mostly untested so far.
Making mods
Pick this if CSDK 12 will not start, a compile fails, or your change never shows in game.
Pick this if a hero T-poses, the camera sits in the middle of the screen, or the health bar is at the feet.
