Dead Achievements + Achievement Sounds
A number of achievements in sound packs don't have meaningful indications of when they are triggered or have missing fields like title/description or aren't triggered correctly. With Escalation, there are even more events that could be triggered.
Yes, you can read some of the code used in determining these events, but it still needs a bit of maintenance.
There are missing fields or strange strings or failures in implementation for:
SESSION_STARTED
SESSION_ENDED
SESSION_RESUMED
SESSION_SAVED
PER_KILL
HEAD_SHOT
HUMILIATION
NICE_THINGS
REPEAT_CUSTOMER
THINK_THEYD_LEARN
DOMINATION
RECURSION
RECURSIVE_RECURSION
COUNTER_TERRORISTS
MINE_SWEEPER
INTERLINKED
SIDE_KICK
OVERWATCH
KNIFE_FIGHT
ROCKET_PRIMARY
MASTER_JUGGLER
VIP_TEAM_KILL
REVENGE
PRESENT
WATCH_YOUR_STEP
DEATH_INSULT
POOR_CHOICES
MALPRACTICE
SUICIDE_BOMBER
QUAD_DAMAGE
ROAD_RAGE
SHOOT_NEEDLE
DECIMATION
FLYSWATTER
EXPLOSIVE_EFFICIENCY
FRAGASM
PISTOL_WHIPPED
RUN_AND_HANDGUY
SIDEARM_SLAYER
COMMISSIONER
EXECUTIONER
EXPLODING_FIST
PRECIPICE
GUN_BIGGER
BATMAN
FATALITY
SUBMISSION
FIRST_BLOOD
INSTANT_ACTION
It would also be handy to order the achievements alphabetically during configuration, for maintenance. I've been doing a lot of editing and documenting my own pack, and it's a hassle.
