Pretty minor one. :> The bug form in the sticky doesn't really fit this situation, but I guess we can give it a go anyway.
1. What the circumstances were.
Anything. But I guess rolling a character?
2. What happened.
I hovered over the description? You got me. I was actually browsing the XML changes.
3. What you expected to happen.
Nothing. It's just a typo.
4. Steps we can follow to make the bug appear on our machine. This part is important!
Inspect Mods/Core/Defs/TraitDefs/Traits_Singular.xml:297
<description>NAME loves fire. HECAP will occasionaly start fires and will never extinguish them.</description>
Good catch!
To clarify: the typo is the word 'occasionaly', which should be spelled occasionally. I can confirm the error is in the XML file. (Incidentally, I've dumped the Core usages of XML into an HTML help file in my signature.)
