Camera sometimes starts at a map's origin

Occasionally upon loading a map, the camera seems to start at position 0,0,0 (often causing graphical errors) before jumping to the correct position. Whenever this happens, at least when testing a map from ZB (which is where this bug often happens), the "Speeding off to level..." text is visible during the "THIS GAME SHOULD NOT BE SOLD" screen.

This seems to be related to interpolation. I can't figure out how to reliably reproduce this, even from ZB, but I've also had it happen a few times upon selecting a map in Record Attack/NiGHTS Mode.
