you should note what unit this is in, particularly since it says "Min" which
could be interpreted as "minutes"

also I object to using just "bubble" here (in the comment and the var name)
because the period of invincibility also applies to the icon.

Done.

I don't like this implicit cast, I'm used to seeing !!pointer_value_ instead.
Dunno what the style guide has to say about this issue.

[bondd, 2015/10/23 03:32:34]

Done. Windows compile didn't like the implicit cast either. :)

no need to DCHECK since you're derefing on the next line anyway
