Found bug in this stream at 14:50 mins : where player 2s previous choice of class' icon shows on map rather than the currently used class' icon. If you look: Benjamin Magnus is an Apothecary but is depicted on Commissar Roaches map as a Chaplain.
You can see Benjamin Magnus Games : Space Hulk : Deathwing / part 3 . 9th Dec 2017 Youtube vid at 15:05 mins to cross reference it.
It's quite entertaining these streams by two newbies who didn't do the tutorial; they have alot of compliments and interesting viewpoints, through the chapters.
