Fixing HP and resetting EXP for Crypt bosses

HP were buggy. 80,000 HP weren't real, thanks to the limit of 65,535 HP those mobs actually had (80,000-65,535)*mutation HP.
Also I deleted the fixed EXP of 7,812 as they were quite unfair -> testing after the changes showed 27,000~40,000 EXP - better :)
