No interrogation possible altough prisoners have intel

[Surica-11]

I don't have the "start interrogation" button anymore when I click on the interrogation chair. All except one prisoner have intel. Interrogation worked before but now I get the following error message:

Need more information about pawn you are trying to interrogate.

Sorry for late reply.

I realised that I captured a wild pawn and after that the interrogation button disappeared.
