A.There is an issue that will cause challenge 127,Cut! not to load,so dont load that,and forget about loading challenge 130,They Have Adapted,as you cant kill the black zombies,though challenges 128,129 and 131,will allow you play as Classic Smoke.
B.You cant load challenge 73,or 75,76,though 74 and 77 will work fine with tarkatan soldier a.
C.In order to play as generic fighter a,load challenges 82 and 83,DONT load 81 or the game will crash.
D.With Cyberninja LK4D4,you cant load 37 or the game will crash,load 38 to 41,those will work.
E.Classic Jade is playable from challenges 13 to 17.
F.Here's a list of modified challenges from me: 30:The Unlikely duos:Part 1(Super WIP):Play as MK1 Ermac and npc_basemale and kill your opponents and perform a fatality or babality.
 55:Your time to smoke(WIP): Kill 6 zombies in the street rather than the desert,but watch out,you have a short time limit!
 56:Mess you up twice(WIP): Defeat Scorpion by hitting him in different parts of his body,his location is on the street(not the desert,another change)
 57:The Burning Man(Super WIP): Kill the suicidal Tarkatan Soldier by pushing him over the edge of the arena.
 58:Out on a Limb 4(WIP): Defeat your opponent by tossing your limbs.(this is done on the godofwar bgnd,another change,as this arena never shows up during challenge tower)
 59:Resurrection:The Revenge(WIP): After beating your previous opponent,Sheeva has challenged you to a match to the death,once you defeat her,you must finish her with fatality or babality only(no stage fatalities)or goro will come to her aid and make matters worse.(again played on the godofwar bgnd)
 64:BALLIN on the PSTRIPLE!(WIP): Face off against npc_basemale as your damage starts to reduce 2% every attack performed.
 65: Dark Powers(WIP): Fight and defeat npc_fightingdummy_male otherwise known as Ruutuu,who's trying to steal souls from the soul chamber to gain powers and start a war,while your speed decreases every second that goes by.(both of these challenges are played on the soulchamber rather than livingforest)
 :225: The Impossible Challenge: Just play.(great as a prank to your friends as i stated earlier).
 266: The Duel 2(ULTRA WIP): The Original Sub-Zero has challenged you to a Duel,think you can shoot him faster?(done on the street rather than desert)
 267: Relock N Reload(WIP): Smoke has challenged you to only use your special moves and xray against him on shang tsung's throne room,think you can beat him?
 275: Army of What?(not so WIP,i need to change the title and description and challenge tower pic for goro that's all,any good title for this one?)Can you defeat 3 Classic Reptiles in a row in one lifebar?(done on subway rather than graveyard)
 289: I am Who?(WIP): You will change into different characters every 20 seconds:for example:npc_basemale and char_goro.
 G.Another issue is that for some reason,sometimes when i finish challenge 74 with Tarkatan Soldier,the game will crash.
H.In order to play as Classic Reptile,load challenges 248 to 251,but DONT LOAD 247 or the game will crash.
I.The entire Test Your Sight ladder has been modified,though with Goro's Lair Oni,if you screw up with him,as soon as you pick the wrong cup or head,the game will crash.
J.The first 3 challenges or first half of the Test Your Strike ladder has also been modified.
K.Soul Glow(95)has been modified,requires cyberzero_c aka MK3 Cyber Sub-Zero,and it's wise to have all 4 dlc packs installed,as several of my modded challenges require dlc characters or costumes in order to work.
L.Challenge 10 was modified,also known as The Impossible Challenge 2,just play and you will see why.
M.In order to Play as Ruutuu,select challenges 176 to 179,dont pick 175 or the game will crash.
N.To Play as Classic Noob Saibot(and a challenge where you can play as Goro's Lair Oni)pick challenges 260 to 263 but dont pick 259 or the game will crash.
O.Another Towerblock has been modified,dont play challenge 217,but you can load challenges 218,219,220 and 221.
P.If there's anything i forgot to mention i will post it on my MK9 Misc. Mods Thread,but feel free to tell me if you need help with my mods!
