Bugs

 * If Flak is enslaved and the player is not successful in subsequently removing the collar to free him, this will cause Shrapnel to disappear from Rivet City and no trading will be available. He will also be found around Inner D.C. usually fighting raiders, if you open dialogue with him he pretends like he is still at Rivet City.  Observed on PS3 and Xbox 360 version 


 * Shrapnel may start patrolling between Paradise Falls and Rivet City, trading is still possible.


 * If the player chooses to enslave Flak and then releases him from Paradise Falls, he may be found back in Rivet City doing his usual routine. The problem is he is now missing his dialogue options. When interacted with, he will just have a line stating "You saved me from those bastards. I won't forget it." Shrapnel will also mysteriously disappear. This can be fixed by using the "removefromallfactions" command on Flak. On the Xbox version, I freed Flak after enslaving him and when he returned to Rivet City, he wouldn't speak to me at all. Not even the dialogue mentioned by the previous User, he just keeps shifting positions every time I press A. Its troublesome since he's usually the one manning the shop while Shrapnel is elsewhere.


 * For long periods of time and a lot after Doctor Li moves to the Jefferson Memorial, you will find Flak trapped in Li's room behind an Average lock with Shrapnel waiting outside. He will not leave until you break in and shoot him which of course makes everyone in Rivet City start gunning for you. (Seen on Xbox 360 and PS3 versions so far)


 * When Flak is enslaved and taken to Paradise Falls it is still possible to trade with him for a limited time while he's in the adult pen meaning you can access all supplies from Rivet City in Paradise Falls.
