Comment 6 for bug 1162936

I disagree with #5 - bug 1183479 would lead to a wexception("Unknown Queue_Cmd_Id in file: %u", id) and not to the message reported above.

However this bug here is most likely related to bug 1181278 - as in both bugs the reason seems to be the following:
* A higher educated worker was kicked out of a slot for a smaller educated worker
* During this, a request for the higher educated worker is generated and not for the normal worker of that working position.

I haven't checked it in the code, but I am pretty sure, that this must be the case, as it would explain both, this bug and bug 1181278
