The same mission keeps repeating in a loop

[Voodoo_41]

Hello.

 

We created a campaign on Typhoon in Normandy in May 1944. The campaign started well, but we got to a mission to “attack trains near Étretat,” which we completed without any problems. The problem is that now the software only offers us this mission on a loop. Is there a particular reason for this?

 

We've tried changing the objective type settings and setting trains and rails to 0, but nothing has changed.

 

Do you have any idea how to move on to another mission, or at least to another area other than the same town?

Do you get a mission accomplished screen after the mission has been flown? 

Are there clear objectives in the mission? 

Not enough information to really help.

Yes, the mission had already been flown. But I just found the answer...:

The mission box was too small, and Etreta was the only city in it...

I increased the size of the mission box and it works.

 

We reduced this box due to performance tests because we experience lag when we launch missions.

 

Do you know if the Keep Ground Spread option is a distance outside the mission box where units are still created?
