I printed my geometry data to 9 significant figures and found no overlaps or gaps so far, will keep checking just in case though

Tried the geantino test, still getting the same issue and the skipped sections of data output and mysterious jumps to the world volume are still there.

* G4Track Information:   Particle = geantino,   Track ID = 1,   Parent ID = 0

Note that the lines of sensitive detector output are slightly different, I changed the G4cout commands to:

	G4cout << astep->GetTrack()->GetCurrentStepNumber();
	G4cout << "\t" << thePhysical->GetName();
	G4cout << "\t" << astep->GetTrack()->GetVolume()->GetName();
	G4cout << "\t" << astep->GetTrack()->GetNextVolume()->GetName();
	G4cout << "\t" << astep->GetPreStepPoint()->GetPhysicalVolume()->GetName();
	G4cout << "\t" << astep->GetPostStepPoint()->GetPhysicalVolume()->GetName();
	G4cout << "\t" << location << "\t" << bin << "\t" << value << "\t" << energyDeposit/MeV;
	G4cout << G4endl;

Thank you,
