@Sherluck Holmes, yeah I find both the Lucky Hat and the Tight Boots to be really funny additions, love the description of the Tight Boots as well
It probably saved Armitage's butt at the end of the day with that little tweak.
Jenkins and the Formless Thing did indeed fight instantly as he was dragged into CC maybe it wasn't clearly written though.
Yeah I couldn't find anything about the shooting and CC.
I figured a few things
1) If the model is alone it should be able to shoot without any problem at the model in base contact
2) If another model outside of the combat fires at a close combat it could be randomly generated who is hit by rolling 1D6.
3) Large monsters / stuff on larger bases would probably be easier to hit - so maybe the risk of hitting your own wouldn't be that big if the opponents base is larger than your friendly model base when both are in base contact with each other. The alternative would be to check the angle, if you can fire from an angle that wouldn't risk hitting your own model it could be OK.
But really good you brought it up, didn't find it to be a huge problem in this game, but there might arise weird situations in the future. This was also my first "proper" game played from start to finish so I'm steel a bit green about the rules and had to consult the book fairly often to check up on things.
Hope to get another game played early next week when a buddy comes over.
