Flee reduction doesn't match official/iRO Classic Wiki

[Asonael]

Describe the bug
Flee reduction from multiple monsters is not calculated correctly to match official (via iRO wiki classic)

https://irowiki.org/classic/FLEE

Skill bonuses should be outside of the reduction of flee.
Expected behavior (from above): Actual Flee = Skill Bonus + [Level+ AGI + Item Bonus] * [1 - ((Mobs -2) * 0.1)]
Behavior on Hercules: Actual Flee = [Skill Bonus + Level+ AGI + Item Bonus] * [1 - ((Mobs -2) * 0.1)]

To Reproduce
Steps to reproduce the behavior:
Tested on 13 Kukre with 102 required FLEE for 95% dodge, reducing flee to 1. Every attack hits except lucky dodges. Should have 41 flee and dodge over 1/3rd of the attacks if Improve Dodge was calculated outside of flee reduction.

@skyleo is this something you can check in your sources?

In 11.2 pre-re Aegis (this->characterInfo).basicAvoidance is used for calclulating CPC::GetAvoidableSuccessPercent

and CPC::UpdateAvoidableSucPerOnClient is used for updating this value, which does take TF_MISS there into account, when setting (this->characterInfo).basicAvoidance.

So iRO Classic Wiki is wrong, unless it changed later in Aegis, usually unlikely for such basic mechanics though.

What should be noted though is that incorrectly Hercules doesn't cap the amount of enemies that affect Flee. In Aegis only 12 enemies at most can affect Flee and 2 of them are still removed from the calculation. Meaning any amount of enemies above 12 is handled the same as exactly 12 enemies in relation to the flee penalty.
