[DEPRECATED] Negative Trait Formula Fix

The fix has been incorporated into Stellaris in patch 3.11. This mod is no longer needed. What This Does You may have noticed a strange behavior when your long-lived leaders (especially those who are recruited already being 100+ years old) start disproportionally getting a lot of negative traits in a short span of time. NTFF tweaks the negative trait chance calculation formula to prevent such issues. Technical Info 1. Stellaris uses different negative trait formulae for immortal and non-immortal leaders. Immortal leaders are not affected. 2. Base yearly chance to get a negative trait for non-immortal leaders is 5% and is affected by a multiplier. The chance caps at 25% and obviously can't be less than 0%. 3. Stellaris uses this formula to calculate the multiplier (comment copied directly from Stellaris formula): # Eligibility increases for every full 20 years of AGE, every LEVEL, and every PENDING Negative trait. # Eligibility decreases for every CURRENT negative trait. This means that for every 20 static years leaders get +1 increments in the formula. Vanilla formula is balanced for leaders with default lifespans of 80-100 years. Leaders that have longer lifespans and start of older age (for example the Dark Elves from Elves of Stellaris are at least 100-400 years old when recruited) are completely screwed by it: they start with 5 to 20 added to multiplier formula. For example, the yearly chance to receive a negative trait for a level 1 non-immortal leader that is hired already being 300 years: 5% * (300 / 20 - 1 - 8 - 0) = 5% * 6 = 30% but caps at 25%. Compared to a fresh 30 year old leader: 5% * (30 / 20 - 1 - 8 - 0) = 5% * -8 = 0% (minimum). This mod changes the divisor in the formula from static 20 to leader_max_age / 4. The more long-lived your species is, the larger the interval between age-related increments in the multiplier. For leaders with default max age of 80 the mechanics is unchanged.
