ОФБ-7 // FB-7 (satellite)

in the tactical autobattle, it moves the troops forward as much as possible (as usual), and then, if the enemies reach them, the game ends; if they don't reach them, then the option to retreat appears. In your case, on the expert tactic, the pikeman was moved as far forward as possible, which allowed the vampires to reach him and kill him, so the option to retreat was not offered :) you need to be attentive and read what QuickCombat writes; I don't think this is an isolated case with such a breakdown...
