As title say, this has to matter with some arrested NPCs.
We, in the Commerce Guild tried all the ways to figure out who had our NPCs under arrest since many years, Glaeken tried (probably not in the best place since topic was closed quite fast).
However, it seems only some admin help could help us to free our wookiees workers before they die starving in a backwater jail.
As it was told previously, if we could have dealt with this in a player to player manner we would have done it, infortunatly this mess resulted on a long run with many leadership change.
If any admin give us at least some hope to resolve this issue anyday, this could be a good start.
PS: If you need a list of different attempt we did, or the list of NPC names feel free to reply.
Obviously there is some bug related to this; my guess is that the arrester has since been killed or deleted for inactivity, so it no longer displays properly. Please make a bug report so a developer can resolve this, since they are unlikely to spot this here. This is probably an issue with many other arrested NPCs throughout SWC, so hopefully they can all get dealt with at the same time.
