Playing Muton's version ufoai_2.3-dev_23753...I ran into a funny thing regarding rxn fire!
Rxn fire seems to work okay, allowing the aliens a fair chance to fire back but I notice the following:
1.) Alien A is equidistant from Ensigns Dead Meat and Gunna Bite-It. Deadmeat heroically fires twice at Alien A, hitting both times with the second shot eliciting a return shot from Alien A. Dead Meat survives!
Gunna Bite-It, due to line of fire problems (but not line of sight), moves to a better position, each step taken eliciting reaction fire from Alien A not upon Gunna Bite-It but instead the unfortunate Dead Meat. Dead Meat is shot at least 4 times more.
I guess the point I am trying to make is that rxn fire works well (i.e. allows aliens to try to kill humans) but the targeting seems off? Is this really an issue or the way it is intended to run? If this is the intended procedure then I apologize.
