I only listed other known bugs in the game, but there are actually more.
Regarding the fact! I wonder what you want me to answer? Should I name a scientific institute? I said practice! For you, I'll explain - this is what you learn not by reading, but by playing!
It would have been enough for me if you, for example, answered like this: "Comrade N conducted 10 test battles with 'Soldier's Luck' and 10 battles without it - in both cases, 'Stun' only worked once"; your reference to your own practice is not valid, because the practice of other players shows the opposite.
