Hey yep i've been able to finish the mission a couple weeks after I've sent the message, this time the UH-60 behave as he should have, so everything went well after that !
Except this bug and few problems with incorrect ADF/homing, I've been able to complete the campaign without any major issue and it was very interesting and a ton of fun to play, maybe it lacks a bit of different voiceover but I enjoyed it very much. Thanks for the great work !
