`Content\Shaders\DarkShader.xnb` File not found
The "Dark Levels" mod section copies a file from mod directory to game's folder. But it works for me, with mod subscribed as Workshop mod. Maybe you lack file permissions on your end?

`Content\Shaders\DarkShader.xnb` File not found

I think I fixed that. It wasn't crashing for me because Duck Game wasn't deleting that shader off its directory on exit like I though it would.

the mod causes the game to crash on startup. here's the crash report:

Mod "Gatling" crashed. Mod disabled. Try running game again.

"Shaders\DarkShader". File not found.

Try re-subscribing then, because I just checked and the "DarkShader" issue was fixed

Can you upload "DarkShader" on cloud and post the link, cause it still cause crash?

It's in the mod's folder, in Workshop Download's directory.
You're a modder, do you have an idea why it crashes for half people, and works for the other half?
Erik has an idea it's a regional thing, issue related to Windows' language

I don't really have any idea, I just removed it from \Effects and created new folder Shaders (that helped), maybe this folder name is reserved or smth
