I noticed a new, previously unknown (at least to me), bug with archers firing twice.
Let's say elves are shooting at 25 dragons.
1) Initially, the elves have 24 shots.
2) After the first two shots, 10+10 dragons are killed. 22 shots remain.
3) After the second two shots, 5 dragons are killed. The elves will have 21 shots remaining.
4) We make 10 more pairs of shots, after which 1 shot remains.
5) We shoot! And... the elves make both shots, even though only 1 remained.
P.S. I didn't use this bug during my playthrough.
It's good that the archers have 25 shots this way... :), but this could have been expected, knowing that artillery shots reduce the total. I decided to check this specifically, and it turned out to be very useful. And if you divide the elves into 2 stacks (there are no problems hiding them behind a power field), this gives you 2 extra shots with a greater chance of a lucky hit ;)

I still think it can be forgiven the first time.
I think you're right :D

And when can we expect stages 1-3? :)
