I was playing my Homeworld mod for Entrenchment.
The other mesages were just like the one above only they were like:
DebrisGenericLarge0.mesh
DebrisGenericLarge1.mesh
DebrisPhaseGenericLarge3.mesh
DebrisPsiGenericLarge3.mesh
KAD_Swarmer.mesh
Mostly the number just changes and sometimes the race.
and so on. I get about 7 or 8 in a row before the minidump
Seems like to me if the game can't find these meshes it would minidump right off the bat.
