The First step is deleting the registry, since the game skipped one second and that's why the achievement didn't drop.

To do this go to press: "Windows Key + R"

Then you'll need to enter: "regedit" into the box.



After that go to: HKEY_CURRENT_USER then SOFTWARE then BCHwaves

When you're inside that folder delete the map of the game you're having problems with.

Now go to your Steam Client.

Go to the affected game in your library.

Left click on the game and go to properties and then in the upper part of the window press on Local Files.

Then press "Browse Local Files" and now you should be in your steamapps folder of the game.

Now you delete EVERYTHING in the game folder.

Example:

Now you're done with this step.

Now you're almost done!

Go to C:\Users\yourusername\AppData\LocalLow\BCHwaves\"the affected game"

When you're there, delete everything in the folder of the game.

This is the last step.

Just uninstall the game to be sure that everything is reset.

Now install it again and play the game or wait until the achievement is dropped.

If it's for example "new_achievement_name_1_4" then it will drop almost instantly
and if it's "new_achievement_name_45_2" then it wil take some time, but be patient!

Now you hopefully have your achievements!
