underscores in style names crash Flare 7

[rlauriston]

I created a new h1.not_in_toc style and builds started crashing with "Collection was modified; enumeration operation may not execute."

Took the underscores out of the style name and everything's fine.

Should I report that as a bug? Doesn't seem like Flare should let you save a style name it can't handle.

Odd; I just tried the same thing, and I was not able to duplicate the issue. I created h1.not_in_toc and I could build just fine. I think you should report it, because there may be something else going on, but I'm not sure what.
