[1.1 Royalty] Invisible Prisoners on Royalty Quest

[Kollateral]

When accepting a 'royalty' quest to protect a prisoner of group of prisoners, a notification appears stating the prisoners have arrived, but they never show up on the map. After a few in-game days, I get a notification that the prisoner has died or left and the quest has failed.

We'll address this for sure.

Do you still have the savefile from before accepting the quest? It would help a lot.

Same problem. Can't attach file because file is too large. Here is link to Google Drive.

It looks like one of the mods is at fault:

Cities namespace, perhaps RimCities?
