Ok well f**k me.
So I chose 2014 and handpicked the roles I wanted differently.
Then the new roles were gone again.
So I edited and added everything like what's written here.
And then I've got sidekick and such, but doc is suddenly changed again as are a few other roles.
I just don't understand I guess.

I deleted the sandbox script thingie and installed this; but it's still odd! Now some icons are what they used to be in original but others aren't. I tried original, but it has a really weird hooker for example. And then I tried 2014, but bodyguard is weird and mafia hat is changed and it has a fool that I actually kind of like so the fool can stay. And I tried riddlers and they do have the correct bodyguard but lots of other things are weird.

I'm almost ready to reinstall the sandbox thingie and take the downsides there for granted.

I just want my roles back! :(

For those who are interested in Riddlers' classic icons, you may notice that there is a few roles (ones made since 2014 when he posted it) that appear as blue: the Tinkerer, Cupid, Don, Toreador, and Psychic. I corrected this issue for myself.

All you have to do is edit the user style (by going to the stylisth tab, right-clicking on Classic Icons for EpicMafia, then hit edit) to do this:

Change the sprite sheet to http://i.imgur.com/GORntOR.png:
/*SPRITESHEET GOES HERE*/
.roleimg { background: url("http://i.imgur.com/GORntOR.png") !important; }

Add the following lines after the final role at the end of the script:

.role-psychic { background-position: 0px -2860px !important; }
.role-tinkerer { background-position: 0px -2880px !important; }
.role-cupid { background-position: 0px -2900px !important; }
.role-don { background-position: 0px -2920px !important; }
.role-toreador { background-position: 0px -2940px !important; }

And... to fix sidekick (new role lucid added), add this to the end after the toreador:

.role-sidekick { background-position: 0px 0px !important;
background: url("http://i.imgur.com/JODjTO6.png") !important; }
