Weird message in specials tab

I've been working on some races and abilities, and where possible, using or replicating abilities that already exist, and then tweaking.

I've run into a really weird problem. In some cases where I duplicate existing abilities and tweak them, they pass when I use the "Test Now" button, but for some reason, when I try out a character, in the Specials tab beside the ability, it says "nyogoth qlippoth" in brackets beside the ability. I've gone through every Tag, Eval Script, Eval Rule etc. and I can't find references to nyogoth qlippoth anywhere. I've got no idea how that value keeps creeping into what I've done.

Looks like the kind of weirdness that happens with Test Now every now and then. I'd recommend using the Quick Reload (from the Develop menu) instead; it takes about the same time, and seems to be more reliable.
