Apologies if this has already been covered.
As far as I know there may be up to three victory conditions in a scenario.
1) Occupation of cities, bridges or other objectives
2) Occupation of certain hexes (yellow -> green)
3) Destruction of certain enemy formations.
When 1) is fulfilled, the scenario is ended automatically, even if the conditions in 2) or 3) are still not met.
Please let the scenario continue until all victory conditions are met.
Presently, you need to wait with the occupation of that last objective.
the priority of the objectives is the designers choice.
And occupation is not always leading to victory depending on the map and its conditions.
The conditions can act in combinations and as single entities for different victory types.
There are more victory conditions, but not all possibilties are covered yet.
E.g. you could make the destruction of bridges a goal.
Also on some maps you have to save own units, occupy and repair bridges to win.
All can be set as wanted, leading to an end on their own or together.
If you refer to a certain map, please name it and we can discuss the very case.
