I tried to save/load and roach don't have tail again or tail hanging in the air and roach don't have ruff. What can i do?

Tested on patch 1.30. I tryied to save with nude/dressed roach and mounted/not mounted roach. Nothing help. =(

Enable the console and mount your horse (important). Now open the console and type:

KillHorse()

When that's done, recall Roach and she will have her tail back.

You already suggested me that, but i said i want to wait fix because i don't have mods. Developers said that they fix it, but bug is not FIXed.

You don't have to install any mods. Open up your '..\Documents\The Witcher 3\' folder and you will see a file called 'user.settings'. Open it up in Notepad and find the entry called [General]. Edit it so it looks like this:

[General]
ConfigVersion=2
DBGConsoleOn=true

Remember to do this while the game is closed. This will enable the built-in developer console, which can be opened with the Tilde key.
