This appears to be happening to me at the moment. It's the sinper rifle hunt with the deers. The last deer doesn't spawn. I even tried restarting the mission, but no luck. I find it so annoying because it's the last "Path of the Hunter" mission I need to complete. 

I recently started playing RE5 on PC and so far I've really been enjoying it.

There's just one MAJOR problem that is really upsetting me. 

Even when I save my last checkpoint before exiting, I always end up back at the beginning of the section when I decide to play some more later on. The last time it happened I was put behind at least twenty minutes. It happens no matter what every time.

Is this some sort of glitch or is this normal?

If this is normal then whoever decided to design it this way is definitely mentally challenged.
