Fix!
Ok, I studied the mission's trigger zones, I tried expanding some of them including the one that is supposed to be for the allied infantry coming from Metaxa LZ.
However It still didn't work so I decided to try changing the triggers a bit,
There are originally 2 conditions for victory:
First: you destroy the convoy west of the LZ and report it
Second: allied infantry squads like Ford, Uzi, Springfield reach the trigger zone where the enemy infantry originally was + less than 21% of the enemy infantry alive
I simply changed the second broken condition to the first one, so now the victory only depends on you destroying the convoy and reporting it, than up to 30 seconds your mission should be "successful" and you should get all the success reports...
This is the only way that actually fixed it for me and now I can rest in peace. :smilewink:
