func_802AF314()

void func_802AF314

(

void

)

Appears to initialize some variables and struct members after course displaylists have been parsed.

Bug

possibly bug. Allocate memory but not increment the pointer. This is bad, dumb code, and more importantly it's bad dumb code that doesn't make any sense here. It is incremented after this function completes using a different variable. Not good.
