Unpredictable triggering of skills for units

[pjd79]

Expected behavior

the ninjas must dodge whatever the number they are.

Actual behavior

Here is the first round of a fight between 18 ninja dodge the shoots of 50 swat unit.

[A] ninja (1) dodged 5935 DMG.

[A] ninja (1) dodged 5935 DMG.

[D] (1) with 50 x swat with 14000 HP take 1420 DMG from [A] (1) with 3 x ninja "dodge".
[D] (1) 44 x swat are left.

The same first round bettween 20 ninja and 50 swat:

[A] (1) with 20 x ninja with 6000 HP take 5935 DMG from [D] (1) with 50 x swat "multiplehit".
[A] (1) 0 x ninja are left.

[D] (1) with 50 x swat with 14000 HP take 1580 DMG from [A] (1) with 4 x ninja "dodge".
[D] (1) 44 x swat are left.

what is surprising is that with more ninjas in combat, the fight is even more unfavorable to them than with 2 less ninjas

Steps to reproduce the behavior

Make a fight in the simulator between 18 ninjas and 50 swat and 20 ninjas and 50 swat

This also seems valid for the skills of the other units. I noticed a bug in triggering the mercenary's bulletproof skill that was also triggered unpredictably

This is also the case for bouncers.
You can find situations where adding more bouncers reduces the number of surviving bouncers due to non-activation of the shield talents.
Two line of one fight against the same army, and only changing bouncers quantity.
With 900 bouncers ( last attack from the defending army):

[A] bouncer (1) used his (1) shield. [A] (1) with 784 x bouncer with 125519 HP take 7677 DMG from [D] (4) with 40 x elitesniper "criticalhit".
[A] (1) 841 x bouncer are left.

With 925 bouncers:

[A] (1) with 809 x bouncer with 113339 HP take 7677 DMG from [D] (4) with 40 x elitesniper "criticalhit".
[A] (1) 754 x bouncer are left.

To resimulate the same fight, it's a batttle between 900 or 925 bouncers, 4 big Mamas, 18 ninja, 70 bazookas against 135 policeman, 68 boduguard, 56 swat and 40 elite sniper
