I tried to replace the problematic mission (FS1A2M02.fs2) with the next one (FS1A2M03.fs2), since I'm not sure how FS2 link the mission I figured it was best thing to try at worst I whould have to play the mission twice.
Well now I have a new problem ! I can't complete the mission ! Well I did finish the mission successfully and had the nice "you did fine" speech, I was also told I got a nice medal (be I don't see any medal) and when I click the arrow to go to the next mission, it says the mission was a failure and that I have to retry !
I retried the mission a couple of times (at very easy and medium) and completed both objective (checked with F4). Still I'm stuck. Now, I'm wondering if it's because of my mission switching or because this is a other mission to add to the 1.6 check list !
BTW, the port interceptor missiles seems very different than the FS1 ones (the Port's ones are more accurates and do less damage)
As always any comments or suggestions is welcome
Note: I still think this port is quite nice and being a programmer I understand how bug finding and testing can be long, hard and frustating !
