I got V. 3.3 and can´t get out of mario cam sometimes, but the reset allways works. I think it happens after resetting while in mario cam. Try to avoid that and just die and reenter if it happens. Thats the only advice I can give

The level reset code does not include camera-fix, but you can add those lines.
