I paid a hard price for your game, as I bought it with the hard rulebook copy. But after many scenarios, I decided to uninstall and go back to the old Flashpoint campaign. The last scenario "Steel rain" was just too much. The game is broken in many places.
How on earth do the Russians move so fast with orders dealy 51 min vs mine 32? Do they set a path from move number 1 to the end of the whole scenario??? Why do my units move one hex only after 50 min pass since the order??? They have not been in the fight, they moving far away from an enemy, not under fire, and HQ status is ok.
Why my M113 ATGM is not moving for over 40 minutes after receiving an order on the road, but after Russian tanks are 3 hexes from them, shoot at my M113, kill it 4 units out of 5...and M113 immediately move away? So they can`t move for over 40 min on the road, but sure they can run really fast!
I was using Cobras many times and they have been usually working ok. In this scenario, they have in their sites the whole road full of enemy Tanks and BMPs, but they did not shoot a single time in the whole scenario. BMPs shoot down 1 of the Cobras, and they just run away, crying to HQ. And I tried again and again with 100% ammo and NOTHING.
I did not order an air strike when Tornados reinforcements arrived, but somehow One happened immediately, a stupid one in the middle of an enemy (lost 1 Tornado), and after some time, when I wanted one and ordered Airstrike, all have been canceled and never happened.
Fix pathfinding by units because atm it is broken. Just one example here: How AI thinks it`s a faster route??? Uphill, downhill through the forest not on the road...

And the last one. In one scenario after the enemy lost 70% of his forces, I received a victory, 6 out of 7 stars. The enemy has been beaten. So I was like "Sure, let's finish them off, as my 3 Units of Leopards 2s x3 have been closing on an enemy". At this point AI should be holding their positions, trying to hold what they conquer, they should have problems with communication or supplies...And guess what? They move faster than me, with no problems and I almost lost a scenario! 3 stars out of 7 after times run out! So what about this?
My main problem with the game at this point is: the AI just switches orders on the move, to move here or there without ANY DELAY. AI is not waiting in one hex for 40-50 minutes before the next move, as in your first game. So, do AI is planning 20 waypoints at the beginning of the scenario, or simply is just cheating?
I don`t have any data, so only my words.
Please, fix your game, because now it`s just a waste of time. And frustration...
Anyway, I just have to cry somewhere.
Take care guys. I will try this game again after a 1 year or something. Good luck with fixing bugs.
