They made a four-digit code for old clothes and accessories (except for 0001 and 0002), which they added to the Tailor shop / wardrobe.
They can be replaced.
example 0002_KunN to 10160_KunN
core and physics do not have one symbol at a time
but just add from impossible
from changing the total number of symbol in the code, the game gives an error
so you have to take them from somewhere
take the symbol you can from the string skeleton number or "bEnableBoneSpringAngular" (in the case of the last line, in different skeletons it has a different name, but not much different from the one I submitted)
In skeleton 00050678 (0002_KunN)
from the line with the number of the skeleton "00050678", you need to delete two symbol (two any numbers)
the fourth symbol in front of this line is the value determining the number of symbols in it (09 = 8 symbols, 07 = 6, 05 = 4, 01 = 0)
subtract from "09" two symbol, replace "09" by "07"
now we have two free symbols
replace "0002" with core and physics at "10160"
and just like with the skeleton string
find "0A" before "10160_KunN" and "12" before "10160_KunN_Physics"
and increase their values by 1
completed
example 10160_KunN to 0002_KunN
in this case, one more symbol is obtained
replace "10160_Kun" to "0002_KunN" and "10160_KunN_Physic" to "0002_KunN_Physics"
at the end of the lines there are extra symbols
they must be nullified
I hope I could explain
