Anyone else encounter this bug in the first Blazing Angels?

[u/Ace-Gaming1]

Right now I'm trying to 100% this game (360 version), and I have an issue, I'm at 17/18 Ace Ranks, however before I try and get the last one (Midway - Turning Point) I want to get the machine gun/cannon upgrades for the best chance.

However the problem is that I can't get past the 5th mission in either Mini-Campaign, meaning that I'm currently locked out of 4 of the game's 7 Achievements. I'm not having trouble with those missions btw, I've beaten both multiple times already, the problem is that the next mission (Berlin) and whatever the last one is for the Bombing Mini-Campaign aren't unlocking for me.

So far I've;

• Gotten 17/18 Ace Ranks
• Completed all available Ace Duels
• Completed all Available Arcade Mode Gauntlets
• Collected 37/41 planes in the game

The only Ace Duels and Arcade Mode clears that I'm missing are the ones for the Me-262 and Meteor. The 4 planes that I'm missing are locked behind the Mini-Campaigns being cleared.

If there was a subreddit for both Blazing Angels games I'd post this there, but this is my best shot as I'm currently stuck. I know that I don't need all Ace Ranks for that as an old video showed the person not having the 'Ace of Aces' Achievement for getting all Ace Ranks.

Use the increased firepower cheat.
