Accidentally unlocked archivments

Basic info on the update:

• you now dont have teachables anymore. you unlock perks by prestiging. prestige 1 on dwight for example will unlock his 3 teachables bond, prove thyself and leader on every other survivor you have at tier 1. meaning you dont need to find them on others bloodwebs anymore, you directly get them into the inventory of all characters.
• prestige 2 and 3 unlocks the perks on tier 2 and tier 3
• prestige 4-6 will unlock the bloody cosmetics, but you keep them if you unlocked them already before the patch
• prestige 7-9 will unlock perk charms of that character. which is their 3 unique teachable perks icons on a square with purple backround
• prestige is now capped at level 100 and after matches you see the prestige level of these characters, where you used to see their grades/ranks

For having put a lot of BP into your chars before the update, there was a benefit logic to reward that. The rule of the update was as follows:

• for several perk levels above 50 you get a free prestige level. regularly you have around 50 perks (tiers, meaning 3 perks at tier 2 count as 6) at level 50, so the offset was 70 for the first prestige level for free and then for each 50 more tiers (70-120 perk tiers gave one free prestige level, 121-170 gave 2 free levels, up to a maximum of 6 free prestige levels I think)
• for each prestige level you already had, you would get 2 additional on top. so a prestige 1 character was pushed to prestige 3, prestige 3 was pushed to p9
• the prestige *3 multiplicator and the perk levels were adding up, but the free prestige buff was capped at prestige 9, so there was no difference between a P3 level 1 and a P3 fullperk.
• having a character on P3 before the patch unlocked a fancy portrait with animated scratchmarks in the background
