I thought a "hotfix" was when you applied a patch to a hot system, that is a system that's online and running.
But aparently BB uses another definition... but regardless, I find it quite amusing that for the half a year I have played, every update has resulted in one, or in most cases several, "hotfixes"
The first time I experienced an update to TSO I was surpriced that the update would take several hours. I'm used to updates for online games only requiering a restart of the client/browser-window, and only rarely a short downtime.
