SaOk: Thank you for your time to play through this campaign and the review!
I'll not make deep changes already in this campaign, because of lack of time, so I'll not add reinforcements in 6th mission, but of course I'll fix the bug in the script at mission 7th and the typos (except the takistani guy's text, because he don't speak English...
Unfortunately I knew the problem with the chopper insertation and I tried to solve in many way, but I couldn't. There are many parameters in that situation, what made the problem harder:
1., the convoy are move and I (designer) don't know when the player will stop it: it could be anywhere in a very long road. So the solution to put an invisible H in design time in not an option. I have to calculate it in runtime, but it's extremly hard to me.
2., This is a slim valley and BIS choppers AI has a little problem with these terrain...
When I tested this part of this mission I found that problem many times and - as a player - I could solve it to reload the last (automatic) savepoint and try the insertation again. And many times, the second try works well.
