They are not a fixed 76 bytes. The first int of each record is its length,
and while most placements are 76, every track also has eight of 140, two
of 80 and one of 336 - 560 on Paingod's. Striding a fixed 76 landed
mid-record on those, and hunting forward for the next plausible
quaternion then locked onto arbitrary bytes: that is where the impossible
class ids came from, and the "resource id" 1065353216, which is
0x3F800000 - float 1.0.
Reading the length instead, all eighteen tracks parse to exactly their
declared instance count with no bytes left over. That is the check that
was missing before.
It does not change what gets drawn, because the extra records were never
drawable anyway. It does mean the parse is no longer guessing.
