One line summary of your issue
Reinforcement announcement, but there are none.

Please explain your issue is in as much detail as possible.
When I reach the ennemy base I must destroy, the "robotic girl voice" announces there will be reinforcements.
Yet, this mission has no reinforcement at all.

Steps to reproduce the issue
Reconquest (destroy base) mission on Birmingham.
Destroy ennemy guarding lance.
Destroy Turrets.
Walk into base -> voice announcement.
Destroy buildings -> mission end.

Sometimes one or more enemies get stuck at the edge of the map. When this happens I can walk around the edges until I find them. They don't always defend themselves so it can be a bit immersion breaking.

I got that once, but this is not the case here.
There was actually no reinforcement.
When there is, an objective indicates it (as main or sub-objective), it was not the case here.

Reinforcements are broken all round, I think - I usually get a warning and they're there immediately - often as soon as the main objective mechs/vehicles are. They need to be spawned in a set number of turns after you initiate combat and from a map edge you've not got in sight - we can't field 2 lances but (even with the difficulty turned down) you often end up facing 2 lances of enemy (often heavy) mechs...
