Verifying integrity of game cache fixed it for me.

[SOLVE] The only issue i had for this one was running compile: full and light: high. And i thought it was done and that "link" was optional but turning on link and creating the build made my file go from 0,015mb > 293mb

so how do you fix it?

Just click on first "compile: full" "light:high" build it, then also make sure to click on "link" and build the map before uploading & publishing it to the workshop. :) Without "link" the map got about 0,015mb with "link" my map got 293mb :P so make sure to use link on your map! on the launcher

What is the "Link" for you ?
How can you actually fix it??

Should have compile, link and light checked. Leave run off. If you have issues about the fast file still just message me I can show you how to fix it

Hello. I created a map, and when I go to save, it makes a sound, the same sound the PC makes when you change the sound of your PC.
When I build it with the launcher, everything is good, but when I run the map and when I'm trying to play it, i click on "Play" and the game returns me to the lobby and shows a message: Could not read fastfile.
I really need help because I spent a lot of money just for playing Custom maps lolll.

As gcpeinhardt said, ensure the following:
X compile - Full
X Light - High
X Link
O Run

Additionally, make sure you have steam/steam library on the same device (eg. Both on C: or D: drive).

Lastly, make sure you Build your map before you decide to try it (ie. Have all the above, and then select your map of choice by pressing the box beside the name, and then running)

I know you asked a while ago, but I figure if anyone else finds themselves here, doing this got me from hours of frustration to being able to play my own maps.

help me I can't either and I checked everything

You have to debug your map. Check to see if your map is has "done" at the end of the compilation, lighting, and linking. If it doesn't you have a fatal error in your map that you need to resolve which can be seen in the compilation messages on modlauncher. You just debug what is giving you errors. It could be a custom texture that you did not define a material for, or a sound not linking, etc.

There is no generic fix for this.

Easy method*

1. Open steam
2. Locate the game properties for Black Ops 3
3. Go to DLC and check if anything needs installing
