Map Lockshackle from My pet dungeon.
When I captured 2 prisons from the empire, inside I discovered several imperial units. I can not take them in hand, I can not use them for blood money. But I can hit them with lightning.
It happened again on the same map.
My army attacked the enemy base, and at the same time the workers claiming the prison and put enemies in it.
This is my saves. 2 savegames named "bug" and "bug2" - this is a problem with prisoners.
Savegame "Bug-enemy escaping from trap" - for this bugreport Enemies escaping from "trap"
(but it very easy to reproduce)
I've seen it sometimes on some other maps. Sometimes enemy units are getting trapped in prison somehow, but they are not real prisoners, they just cannot leave prison because it has no doors. Your only option is to sell the prison, defeat them and then build it again.
Я видел такое на некоторых картах. Иногда вражеские юниты каким-то образом застревают внутри тюрьмы. Но они не являются заключенными, поэтому их нельзя взять в руку. Они просто не могут покинуть пределы тюрьмы, так как у нее нет дверей. Остается только продать тюрьму, убить их и построить ее заново.
I dont know. For all the time that I play in the WFTO, I saw only 2 cases and they both appeared on the Lockshackle map in one game session.But I can only speak for myself.
Perhaps the common part is that my workers claimed the prison of the enemy while the battle was near the prison.
But I'm not sure.
It often happens when you load a save, as far as I can tell. For example, one of MPD maps has porkzilla imprisoned and surrounded by guards. Sometimes when you load a save, it's not inside the prison any longer, and walks around the prison together with guards (being neutral creature, thus they don't attack it). But if you load the same save again, everything's fine.
As if at some point of loading the save creatures can more freely, ignoring things like prison walls.
Status for prison:
Prisoners Held: 0/1 .
But I see that there are three prisoners
