But then you should make it more clear what the intention is, currently it looks like a bug and is rather confusing for the player.
There are two fuel meters during combat and both show different values.
No, it is the first pair.
Now with 38,0;53,44;33,29:
Edit: Seems you were right, now one missile is also shooting from the center it seems. But I can live with that for now.
There is a WeaponPositions attribute in the aircrafts.xml which should be changed to fix it I guess. Currently it's at 20,44;53,44;33,29 and I believe the first pair is the one for the cannon.
Edit: 38,0;53,44;33,29 seems to be a good value.
When many buildings have finished construction the dialog box won't fit on the screen and I can't dismiss it anymore.
Maybe just say "XX buildings have finished construction" XX being the number of buildings.
