The way out of this situation is to replay the last few days.
As a rule, replaying the last 5-7 days helps.
To make sure, you can try simply skipping turns, loading a save from day N, until day 1 of the new week. And do this several times.
It should help.
P.S. This problem, by the way, occurs not only in Wog, but also in Heroes 1, 2, 3 (I'm not sure about the other versions).
