It just keeps crashing.

If you want help, you should describe in more detail what you are doing.

So I have this mod downloaded, yet it just crashes when I use it. I don't know why.

We using it and seems to be fine, bug splat does happen a little more often to some. map change also triggers it but most unaffected

Is there any other mods I would need to download?

no. This mod is independent, it does not need other mods.

How do you use the mod? Single game or server?

1. Try to reinstall the mod, make sure that you are doing everything as in the description.
2. Check that the mod has fully downloaded:
If you do this for a single player game, you should have two files along this path:
<MY_DOCUMENTS>\My Games\KillingFloor2\KFGame\Cache\2085786712\0\Published\BrewedPC\
ServerExt.u
ServerExtMut.u
If they are not, try to enter the game and exit
3. Check that you have not installed other RPG mods.
In workshop there are old versions of this mod. Their files have the same names and this can cause conflicts.
It is also possible that the game just uses the old version instead of the new one.

Was crashing every time you got a kill for me but a reinstall fixed it.
