It's not hard to repair la... bro mafilax, don't make destiny_scefer scared la..
Got 3 options to handle that problem:-
OPTION 1:
actually in previous post already got a few people asking how to solve this problem.. Simply just
"drill a small hole and insert batang plastic or metal rod in between 2 plastic"
you can even either use a needle not too long, heat up the needle, than pierce it into the leg part, after that, heat up the other side of the needle and pierce it into the main body part. after that pull it out, and apply super glue on the needle with the leg part. (REFER Picture Below)

After Super Glue Dry up, than insert the needle back to the hole poke in just now at the body parts.. than apply super glue there also.. after a while, twist and turn in a few times.. to make it moveable.
Option 2:
Buy a replacement parts from Kotobukiya and fix it
Option 3:
Pay money to other sifu to ask them help u fix it.
Well, Hope u can enjoy fixing this kit
Cheers,

got another option... make diorama with Exia breaking the leg and enter the end year competition...
