Help please any GG person will work!

Ok, major problem since merging my project's stuff with the latest HEAD build.. On loading a mission it crashes right after validating medium.dts, I assume it's going to heavy.dts after that, as that's what it did before. My question is, in the last week or so, have any of you committed something that would cause it to crash on validation of my player model? here's where it's crashing.

from ts/tsTranform.cc

QuatF & Quat16::getQuatF( QuatF * q ) const
{
   [b][i]q->x = float( x ) / float(MAX_VAL);[/b][/i]
   q->y = float( y ) / float(MAX_VAL);
   q->z = float( z ) / float(MAX_VAL);
   q->w = float( w ) / float(MAX_VAL);
   return *q;
}

it validates my light.dts and medium.dts just fine, but on heavy it borks :( I'm not looking for any of you to invest time in fixing this for me, as it's obviously not a TGE problem, but something in my scripts/models. Just curious if you might know what it is?
