when you put your fov to 30, unpause and then put it to quake pro, most of the chunks unload

What I expected to happen was...:
my chunks to stay the same

What actually happened was...:
most of my chunks unloaded

Steps to Reproduce:
1. pause
2. change fov to 30
3. unpause

4. pause again

5. change fov to quake pro

(all of the chunks load again when you start to move)
