Is there going to be a limit on how long you can keep a player in the holding cell of the Avenger? It seems like purposefully keeping someone for extended periods of time could be used to grief other players. Also, what would happen to a prisoner if you switched out the holding cell module for a cargo hold module before the bounty could be claimed?

This is a balance issue that we will want to hold off on until we've done more live testing. One solution being proposed internally is that the passenger would become a 'commodity' at some point, with the player respawning elsewhere to continue playing themselves while you transport an NPC prisoner. With regards to the module change, you would simply be physically unable to remove the module while it contained prisoners (or any standard commodities.)
