Enemy troops revived between waves (alternatively, attacks being ignored)!

Playing "Ali Baba the Young Woodcutter",
chipping away at enemy camps with MMA+1R waves, no blocks involved.
5 MMAs sent in quick succession, all arrived at the enemy camp within a ~4 second time window.
2 attacks were IGNORED by the game, except the generals actually are recovering from their loss.

Sent 5x MMA+1R to enemy camp with 66 Sword Wielder, 48 Mounted Bowmen.
Result - from battle reports:
1. Enemy: 66 SW + 48 MB -> Defeated 7 MB.
2. Enemy: 66 SW + 41 MB -> Defeated 7 MB.
3. Enemy: 66 SW + 41 MB -> Defeated 7 MB.
4. Enemy: 66 SW + 34 MB -> Defeated 7 MB.
5. Enemy: 66 SW + 34 MB -> Defeated 7 MB.
Enemies remaining: 66 SW + 27 MB.

Note how attacks 2 and 4 did not affect the enemy camp, even though:
a. The battle report shows 7 MB were defeated in each attack,
b. An MMA is guaranteed to defeat either 6 or 7 MB in this setup.

This is quite a serious bug!

did you recall any generals - if you do then the general 'next in line' starts fighting even if another general is still fighting - resulting in 2 general fighting at same time - against same number of bandits - when they finish fighting only bandits killed by one of them count.

No recalls, didn't have any reason to. It was a 5x MMA+1R suicide run, no blocks involved.
Also note, the enemy units "ignored" the attack, but my general(s) are still recovering, and their units are dead.
