Now let's take this one step at a time, shall we?
You have noticed that "Game Master" has posted. Correct. If the "Game Master" Has not posted, then that means you did not do it correctly. If somehow you have your action on your own personal post, that is a no no. Reason being is simple: You can go back and edit your own post. While editing your own post is not a bad thing, when you go and send it in again, the outcome will have changed. That is not good because it will not reflect the correct failure/success that had actually happened. So please, allow "Game Master" to post ALL
rolls for you. It is there for a reason.
Second thing you notice is the big fat Critical Failure. As sad as it is to see, it happens even with someone being Proficient in things. In a perfect world, everyone would roll the success die every time in a Proficient die roll, but that is not the case this go around. As you suspect, this is rather grim for your character. Could mean failure or success of the mission. So, now that it is the Mod's turn to reply back, we shall see how bad the situation is for Luna.
As Luna began unlocking the door, a trash can had fallen over, breaking her concentration. This caused her to break her pick in the lock. Normally this would be not such a bad deal, but it had broke in such a way, there was no hope to fish it out. Not even a key that normally belongs in the key hole will work now. Not unless someone just simply replaced the door. While this would have been an easy way in, it seems as if you will have to go about this a different way. The two options left to you are the front door and the air duct. From back here, you notice a ladder that will allow access to the top of the building. Or you can simply walk back around the store and try breaking in again.
A real bummer, but it's not the end of the world! Luna was lucky she didn't loose all her picks or had been caught by a TCPD Officer! Since this is Tier 1, it is rather easy so danger for things like that is rather low. Though, as you level up through the ranks, the more danger you will run into. Please remember that.
So at this point, you will have to decide on the next course of action. Front door or the air duct?
